Dinner at eight may cost more than dinner at six

Under a trial being designed by a mid-sized restaurant group, the price shown on the tablet menu would be recalculated by demand: covers already booked, walk-in traffic, the weather, a match starting at the stadium eight streets away. The same dish at 17:40 and at 20:20 would differ by an amount the group would describe as modest and the floor staff would describe as roughly the tip.

The technology is finished. What is not finished is the sentence. Someone has to say out loud, at a table where two adults have already read the price on the website and one child has already chosen, that the number changed between the pavement and the chair, that it changed for reasons nobody in the building can see, and that it will change back at half past nine.

“The menu would not be arguing with anyone,” a member of the floor staff at one of the pilot sites would point out. “I would be.”

Management would frame it as a discount rather than a surcharge, and would be technically correct. The early price would be presented as a reward for flexibility, the late price as the ordinary one, and the difference between these two framings would be entirely a matter of which number is printed first. The wording would be settled by a committee. The conversation would be held by a twenty-three-year-old on an eleven-hour shift.

The social sorting would arrive as a side effect and stay as a feature. Who eats at 17:30 — pensioners, people off an afternoon shift, families with small children who have to be in bed by eight — and who eats at 20:30 is not currently a question of money. A restaurant is one of the few rooms left where different incomes sit down at the same hour. Priced by the clock, they would stop doing that within a season.

There is a mechanical problem underneath as well. Service is charged as a percentage, so a peak price would quietly enlarge the service charge without anyone behind the counter moving faster, and would shrink it on the shift where the staff are covering empty tables. The pay of the person explaining the price would therefore be set by the same model, with none of the visibility and all of the blame.

Nothing has launched. Similar announcements elsewhere have drawn enough public reaction to be clarified within a week, which is why the most probable outcome is not cancellation. It is renaming.
