A Station During Service.

A station that is busy 75 % of the time sends plates out in a reasonable time. At 95 % the same station, with the same cook, keeps tables waiting half as long again — and in bursts far longer.

A ticket arrives at the pass; the expediter (often the chef) calls it — "ordering two steak, one fish" — and each station starts its part; when the table is ready for its next course, the call is "fire table twelve", and the cooks time their dishes so all the plates for a table are ready together for "pick up". Dishes have very different timings: a steak may need ten minutes and a rest (II.9), a piece of fish five, a sauce made à la minute two. So a station fires its long dishes first and its short ones last, counting back from the moment the table's plates must meet at the pass (XXIII.5).

Behind the calls is the mathematics of queues. Tickets arrive at random, not evenly; when all burners are busy, the next ticket waits. While the station's utilisation — arrival rate × cooking time ÷ burners — is well below 1, waits are short; as it approaches 1 they grow without limit, and a burst of tickets in the rush creates a backlog that takes long after the rush to clear. That is why kitchens stagger seatings, limit the menu at peak times, prepare components in advance, and add a cook or a burner before the station is full, not after. The workshop runs an hour of service.

Below: the time from ticket to plate for each order in two hours of service at a station with the burners you choose, when orders arrive at random at the rate you choose and each takes about the cooking time you choose (course schedule bench, seeded random arrivals), with the station's utilisation.

What you will learn
Workshop
Schedule bench: orders arrive as a Poisson process at the chosen rate over two hours; each needs the chosen cooking time ± 20 % on any free burner; ticket time = waiting + cooking. Utilisation = rate × cooking time ÷ burners (exact for the long run). Same random seed for every setting, so changes reflect the settings, not luck.

Keep slack on the line

With four burners and 6-minute dishes, 30 orders an hour (utilisation 0.75) give a 90th-percentile ticket time of about 13 minutes; 38 an hour (0.95) push it to about 19 minutes — the same cook, just a little busier. A fifth burner at 38 orders brings it back to about 12. The lesson for service is to buy slack before the rush: more burners or cooks, faster components, or fewer orders arriving at once.

Practical habits: read every new ticket at once and note the long dishes; fire long items first, counting back from the pick-up time; keep pans and components ready so that "fire" means cooking, not preparing; call back every order the expediter calls so nothing is missed; tell the pass early if you are falling behind, so the floor can slow the seating; and after the rush, restock the station before the next wave. Plates go out together or not at all — a table's food should never sit under the lamps waiting for one late dish (XXXI.7).

At the stove

Cook three dishes with different times so that they are ready at the same moment. Write down when each had to start.

Kitchen display screens have largely replaced paper tickets in chain restaurants since the 2000s, timing every order and flagging late ones; but the calls — "ordering", "fire", "pick up", "behind" — survive almost unchanged from Escoffier's day.

Terms

Expediter
The person at the pass who calls and checks orders.
Fire
The call to start cooking a table's next course.
Pick up
The call that plates are ready to go.
Utilisation
Arrival rate × cooking time ÷ burners.
Service runs on calls — ordering, fire, pick up — and timing so a table's plates meet at the pass. Waits stay short while utilisation (orders × time ÷ burners) is well below 1 and explode near 1: add slack before the rush.
