QR code on a cafe table: a ping instead of queuing

A twelve-seat coffee shop in a quiet side street. Specialty beans, alternative brewing methods, micro-lot roasts. A place for people who come to work on laptops or read books. One problem – one barista behind the counter.

To order a second cup, you had to get up, walk to the counter, and wait in line. If you had the window seat – someone would take it while you were queuing. If you were deep in something important – breaking focus wasn't worth it. Many people just left after one cup.

The owner noticed the average check was dropping. Not because the coffee was bad, but because ordering again was inconvenient. Hiring a waiter for twelve seats didn't make financial sense.

The solution turned out to be simpler than expected. A small wooden stand with a QR code and a table number was placed on each table. Scan, tap ping – the barista sees a notification: "Table 5 is ready to order." He comes over when he's free.

The first week, guests didn't quite get it. The barista explained to each person at their first order. By the second week, he stopped explaining – people scanned the code themselves, saw the button, and tapped it.

The average check went up by a third. People started ordering two or three drinks per visit. Not because they were drinking more, but because the barrier between "I want another" and "I'm ordering" disappeared.

Regulars appreciated it most. One of them said: "It's like the call button on a plane, but for coffee." The barista now jokes that a ping from table five always means a flat white with oat milk.
