Why Adding One More Staff Member Doesn't Fix Checkout Delays
It's Saturday lunch service. The queue is past the door again, so the manager pulls someone off prep and puts them on a second till. Fifteen minutes later, the queue is exactly the same length.
This is one of the most common fixes in hospitality, and one of the least effective. Adding a body to the counter treats a symptom, not the cause. If the real issue is how orders move from till to kitchen to customer, another pair of hands just adds another person to the same broken process.
Before spending on another wage, it's worth asking a harder question: is the queue actually a staffing problem, or a systems one?
The stat strip
Still relying on a single till to move orders from counter to kitchen? An EPOS built for speed handles that without adding headcount.

Labour already accounts for 30 to 35% of revenue in UK hospitality (UKHospitality, 2025). Adding a permanent till position isn't a one-off cost, it's a recurring one, and it lands on top of a wage bill that's already the biggest line in the business, the same pressure driving more venues toward self-service solutions for UK labour shortages.
Staff turnover in the sector runs at 38% a year (UKHospitality, 2025), and replacing a single team member costs an estimated £3,000 to £5,000 once recruitment, training, and lost productivity are counted in (UK Accountants, 2025). Hire to fix a queue and there's a good chance that person has left within the year, and the queue is back.
Meanwhile, 45% of restaurant operators say they need more staff just to meet current demand (National Restaurant Association, 2024). That's not a resourcing gap that more recruitment closes. It's a sign the process itself needs to change.
Where the real delay happens
Watch a slow till for ten minutes and the bottleneck is rarely the person on it. It's usually one of three things: a till that can't take an order and payment in one smooth motion, a kitchen that finds out about the order late, or a menu system that hasn't updated to show what's actually available.
Modern EPOS systems cut order errors by 40% and reduce checkout bottlenecks by 30% simply by connecting the till, the kitchen, and the menu into one system instead of three (POSZEO, 2025), avoiding the common EPOS limitations growing businesses hit too late. That's not extra staff doing the same job faster. That's the same staff doing less rework, because the order was right the first time.
And the cost of getting this wrong is real money leaving the business every week. UK restaurants lose an estimated £1,500 a week in revenue to wait-time walkouts (Toast, 2025), and 61% of customers say they've abandoned a queue before being served at all (Waitwhile, 2024). Shaving just seven seconds off order time has been linked to a 1% revenue increase for quick service restaurants (Restroworks, 2025), which is really the same arithmetic behind the real cost of long queues and how self-service kiosks boost revenue per hour. No amount of extra hands fixes a queue if the system underneath it is still slow.
What actually shortens the queue
Three changes tend to do more for a queue than a third till worker ever will.
The first is a connected EPOS, so an order taken at the counter reaches the kitchen the instant it's placed, with no re-keying and no shouted tickets. Kayana's EPOS routes orders straight to the kitchen and keeps stock, menu, and payments in sync across the site.
The second is taking some of the volume off the counter altogether. Self-service kiosks let customers order and pay without a staff member involved at all, which is one reason kiosk adoption has been tied to a 40% reduction in order processing time and queues shrinking by 25 to 40% (Lavu, 2025).
The third is fixing the kitchen side of the equation, because a fast till means nothing if tickets pile up in the kitchen. A Kitchen Display System replaces paper tickets with a live, colour-coded queue by station, cutting the chance of a lost or illegible order to close to zero and keeping front-of-house from backing up behind a slow kitchen.
None of these require another wage. They require the order to travel through fewer manual steps.
The real fix isn't more people, it's less friction
A second till worker can only ever be as fast as the system they're using. If that system involves manual re-entry, disconnected menus, or a kitchen working from a paper ticket, the queue will find a new bottleneck within a week of the new hire starting.
The businesses that actually clear their queues usually spend less on labour, not more. They put the investment into the system moving the order, not the number of people standing behind it.
