He is a systems engineer with more than three decades in software. He spent nearly eight years building public key infrastructure systems in C and C++ for Isabel in Brussels, worked as a backend developer at Google on the AlphaFold Server, and before that as a senior systems developer at Transport for London. He is also a director of Reliant Consultants Limited.
Upd8All started in 2022 with something ordinary. Standing in a fast-food restaurant, he watched a crowd build at the collection counter. Everyone faced the same way. Nobody could tell whether their order was thirty seconds or ten minutes off. The staff knew. The customers did not. Nothing connected the two except a name called over the noise.
The usual fixes each cost something. Buzzers get lost and need replacing. Taking a phone number turns a one-off transaction into a record the business then has to hold and protect. What he wanted was a way for a counter to tell a room what was happening without asking the room for anything in return.
The blog exists for the same reason. Most writing about queues comes from companies selling queue systems, and it tends to show. These articles are meant to be useful to anyone running a busy counter, whether or not they ever install the app: what the research says about how waiting actually feels, what a status message needs to contain to get read, and what the alternatives really cost. Where a figure is quoted, the source is linked.
How to Send Crowd Updates at an Event
Outdoor 5G is available from at least one operator across 97% of the UK, according to Ofcom (2025). So coverage is rarely why a crowd misses your message. The harder problem is that nobody collected a name, number or address from anyone standing in front of you. What can you actually send to a crowd…

How to Manage a Salon or Clinic Waiting Room
The appointment time has passed. Someone has just walked in without one. Three people are already sitting down, and one of them has been there longest. Whoever is at the desk now has to say something out loud, in front of all of them. What you can say depends on which room you are standing…

How to Manage Food Truck Order Collection
Food truck order collection looks simple until the practical constraints of a mobile pitch come into play. There is usually one serving hatch, no fixed collection point, and no guarantee of reliable signal or power. At the same time, the business still needs to handle allergen information correctly, meet food business registration requirements, and have…

How to Manage a Café Queue at Peak Hours
At a peak, the lever a café actually controls is the order things come out and who gets served first. Queue length is an output, not a setting. You can change the sequence of work behind the counter today, without hiring anyone, and that changes who stays. Most advice goes the other way. Trim the…

Calling Names vs Digital Alerts: Which Works?
Calling names vs digital alerts doesn’t have a winner. Each method works for a different customer and fails for a different one, and both failures are silent. The person who missed it is standing in the room, and never says a word. One method means a member of staff calling a name or number out…

How to Write a Status Update Customers Read
A status update earns its read in the first line, or it does not get read at all. Often the first line is the only one a reader sees before deciding whether to open the rest. Every rule that follows exists because of that one mechanical fact, not because good manners have gone out of…

How Do QR Codes Work in Customer Service?
A customer stands at a dry cleaner’s collection counter with the phone held up, aiming at a small printed square taped to the till surround. They move closer. They move back. Nothing happens. The queue behind them has stopped moving as well. That scene is illustrative rather than a real venue, but the mechanics behind…

What Happens When You Collect Customer Phone Numbers?
Taking a customer’s phone number turns a one-off transaction into a record. The business now holds that record, with the obligations that come with holding it. The record does not stay accurate on its own. Nor does the reason for holding it last forever. Which? asked its own members whether an old mobile number had…

Can You Use WhatsApp to Update Customers?
It’s gone eleven and the till roll is off. A manager runs a highlighter down a list of eight phone numbers jotted at the counter that afternoon, illustrative only. She wonders whether she can use WhatsApp to update customers the moment their order is ready. The short answer is yes: one condition applies before she…

How Much Do SMS Customer Notifications Cost?
Plivo’s own UK pricing table lists 36 network rows for a single text message. Only one of them matches the advertised headline rate, and it belongs to landlines, not mobiles (Plivo, 2026). A UK venue is quoted starting rates from about 3.3p to 10.8p a message, depending on who bills it. Both are floors, not…

What Data Does Upd8All Collect?
Upd8All is a free app that lets a business send short one-way updates, such as order-ready alerts, to customers who scan a QR code. There are no accounts and no phone numbers exchanged on either side. This article looks at what sits behind that kind of privacy claim. That includes the store labels, the advertising…

How Do Restaurant Pager Systems Work?
A member of staff keys an order number into a transmitter behind the counter. The transmitter broadcasts that number on a radio frequency. The coaster carrying it vibrates, flashes or beeps, and the customer walks back to collect their order. That’s the whole mechanism. Three things follow from it that most guides skip entirely. Does…

How to Tell Customers Their Order Is Ready
A telephone call reminder produced a 61.5% response rate against 56.7% for a text message (BJOG, 2025). That is the only randomised UK trial found that compares two notification channels head to head. It measured whether women aged 60 to 79 returned a urine sample for HPV screening, not whether a customer collects a ready…

Why Do Customers Leave a Queue?
Across 1,673,247 emergency visits in New South Wales, how busy the department already was when someone arrived predicted whether they stayed. People arriving when the department was in its busiest fifth were “3.5 times more likely not to wait”. That is against those arriving at the quietest (Aust Health Rev, 2025). That is a condition…

Do Long Wait Times Cause Bad Reviews?
A bike repair shop owner scrolls through last month’s reviews on a phone during a quiet Tuesday morning, an illustrative scene rather than a real venue. One review carries a single star. It mentions waiting three weeks for a wheel to be trued. The easy conclusion: fix the wait, fix the rating. Large studies of…

How to Reduce Perceived Wait Time
Two things have real evidence behind them. Changing what the waiting area contains, and explaining the wait. Both were tested recently, in hospitals. One on a few hundred people, the other on 23. Neither was tested on how long the wait felt. That gap runs through nearly all of the advice reviewed for this article.…

How to Measure Customer Wait Times
Measuring customer wait times starts with three decisions, and none involves equipment. Name the event that starts the clock. Name the event that stops it. Decide who is inside the count. Only then does the instrument matter. Get one of the three wrong and you still get a number, just not one anybody can check.…

Why Does Queue Jumping Make People So Angry?
An emergency department had a stated priority rule for who gets seen next. Patients were still overtaken in more than 1 in 4 ED visits, and the records show no reason why (JAMA Network Open, 2023). The same skip, done by a stranger in front of you at a counter, gets a different name entirely.…

What Is Occupied vs Unoccupied Waiting Time?
An illustrative scene. A tyre-fitting bay on a Saturday morning: six chairs, a coffee machine, and a wall-mounted screen playing the news with the sound off. Nobody looks up at it. It’s there because a wait with something in it is supposed to feel shorter than a wait with nothing in it. That idea has…

Single Queue or Multiple Lines: Which Is Faster?
Picture a counter with two service points. Before opening, someone has to settle the layout: one queue feeding both tills, or a separate queue at each. It gets decided once and then lived with for years. It’s easy to assume one of the two is simply faster. It isn’t. With the same two staff working…

How Long Will Customers Wait Before Leaving?
No published study measures how long a shop, café or salon customer waits before walking out. Leaving gets counted in hospitals and on phone lines, and almost nowhere else. So the honest answer has to be built from those places, and what they measure turns out not to be the same behaviour. Where leaving is…

Why Does Waiting Feel Longer Than It Is?
In a 2023 study at a Chinese eye clinic, how long people thought they had waited predicted how satisfied they were. How long they actually waited had no direct effect (P = .365, Medicine (Baltimore), 2023). Two clocks run in every waiting room, and only one of them reached the survey. That split is the…

How to Send Updates to a Tour or Event Group
Take an illustrative wet morning at a rural outdoor event. The field marked for parking has gone soft overnight, so arriving cars have to be sent round to a second entrance on the far side of the site. Forty of them are already on the road. The organiser holds nobody’s phone number, because nothing in…

How to Track a Flight for an Airport Pickup
The word to stop trusting is “landed”. On a tracker it can mean wheels on the runway, and on some airport boards it means the aircraft is already parked with the doors about to open. An airport pickup planned around the wrong one goes wrong quietly. This page won’t give you a number of minutes,…

How to Notify Restaurant Customers Their Order Is Ready
Mid-morning in a café, a customer stands at the end of the counter watching the pass. The flat white just put down might be theirs, or it might be somebody else’s, and nothing about it says which. The scene is illustrative, and it’s the ordinary case rather than a bad day. There are four practical…
