CallThatGuy a diner taps once. the right waiter knows.
Built after watching service staff disappear into operational fog.
What it is
The smallest possible interaction between a diner and a restaurant floor.
A diner scans a QR at the table. A short-lived, anonymous session opens. One tap — water, the bill, a manager — and the request goes straight into the right waiter's queue. No app to install, no account to create, nothing printed.
For the floor, it stops being chaos. For the manager, it becomes measurable. For the owner, it becomes a pattern of where service is and isn't keeping up.
Who it's for
Three roles, one shift.
- Diners — one tap. No download, no signup, no menu screen.
- Floor staff — a live queue of requests on a phone they already carry, routed to the right person.
- Managers & owners — SLA tracking on response times; analytics on where service slows down.
How it works
QR → session → queue → ack.
- A diner scans a table QR. A rotated, short-lived token starts an anonymous session.
- One tap creates a request. The session token is never printed — it lives on the waiter's phone, not on a sticker.
- The request lands in a real-time queue for the right floor staff member, who acknowledges from their phone.
- Managers see SLA timings. Owners see analytics across shifts and tables.
Privacy & trust model
Anonymous sessions, by design.
CallThatGuy doesn't ask the diner for an identity and doesn't store one. The session token is rotated, short-lived, and held on the waiter's device — never printed onto a permanent sticker that anyone could later impersonate. POPIA-compliant from the model up, not bolted on.
