The queue is the ad

There is a restaurant in Riyadh with a queue outside it most nights, and the queue is the most expensive thing they own.

Not the kitchen. Not the fit-out. The line of people on the pavement, visible from the road, photographed by the people in it and by the people driving past it.

Watch what it does. A car slows. Someone in the passenger seat looks. The name of the place is now in a conversation that was about something else. Inside the queue, people are already committed, already hungry, already slightly proud of having chosen a place worth waiting for, and they will defend that choice in the review, because nobody waits forty minutes and then admits it was fine.

The queue is doing what the media plan was supposed to do, for free, and doing it to precisely the right people: the ones who are here, tonight, with money, deciding where to eat.

Some of it is manufactured, of course. Fewer tables than the room could hold. A pager instead of a booking. A host who lets the line form before opening the door. I do not think that is dishonest, exactly. It is a choice to sell the wait as part of the meal, and in a city with more restaurants than evenings, the wait is a signal that the choice has already been made by others.

What I notice is the ones that get it wrong. The queue that is too long, so the people who leave it are now telling the same story in reverse. The queue at a place that then serves badly, which converts anticipation into grievance at scale. The queue that is obviously staged, in front of a room that is obviously half empty, in a city where everyone can see through the glass.

A queue is an ad that the customer writes. It only works if the meal agrees with it.
