The Sunday lunch rush
Sunday lunch is one of the two or three busiest shifts of the week. That Sunday the point of sale went down. No tickets, no card payments, nothing.
I stopped seating people for a minute and made one decision: every guest hears it from me before they sit down, not from a server after they have eaten. We took cash where people had it. We handed out gift cards where they did not. I kept the kitchen cooking off handwritten tickets and I touched every table in the dining room, twice if the food was slow.
Comps ran 20 to 30 percent of the day’s sales. That is an ugly number and I would take it again. Nobody left angry.
The same shift, translated
What a restaurant outage and a stalled AI rollout have in common, and the move in each case.| EntryNo. | On the floor | In an AI rollout | The move |
|---|
| 01 | The point of sale goes down mid rush | A model or an API degrades in production | Tell the people it affects before they find out on their own |
| 02 | The kitchen keeps cooking, the front cannot ring anything in | One subsystem is fine and the handoff between them fails | Go find the broken handoff, not the broken team |
| 03 | Comps reach 30 percent of sales | Cost or latency spikes | Decide what you will eat today to keep the trust |
| 04 | Every table gets touched | Every stakeholder gets a status | Keep talking until the system is back |
| 05 | After the shift: what do we change | After the incident: what do we instrument | Write it down while it still hurts |
