The 12-second checkout: anatomy of a café morning rush
We timed 4,200 transactions across 8 Istanbul cafés with a stopwatch. Where each second goes, where guests leave the queue, and which seconds are genuinely winnable.

Checkout time in a café between 08:00 and 10:00 is a different problem from the rest of the day. Once the queue crosses a psychological threshold, people simply don't join it — and the customer you lost never shows up in any report.

Where the 12 seconds go
- 1Item selection and entry: 4.8s
- 2Modifications / adding a note: 1.9s
- 3Choosing a payment method: 1.2s
- 4Card tap and authorisation wait: 3.4s
- 5Receipt and handover: 1.1s
Which seconds are winnable and which aren't
Most of the 3.4 seconds spent waiting on card authorisation sits with the bank and cannot be shortened in software. The 4.8 seconds in item selection, by contrast, is entirely an interface question: 71% of what sells in the morning comes from just 9 products.
Moving the morning menu onto its own screen layout won us about three seconds per cashier. No hardware changed.
Practical takeaways
- Set up a time-based screen layout — don't use the same ordering in the morning and the afternoon.
- Keep the top 9 sellers on one screen, reachable without scrolling.
- Put frequently used notes on preset buttons; free-text entry is the most expensive interaction there is.
- Define a threshold rule that opens a second terminal once the queue passes 5 people.
