Every restaurant has people who book and never arrive, most owners describe it as "a couple a week", and almost nobody has ever counted. It is worth counting, because it is one of the few losses in this library that is pure — the table was held, the food was bought, the staff were rostered, and nothing came back. It is also one of the few that a handful of cheap habits genuinely fixes.
📉 Count it before you fix it
Mark them in the book for two weeks: booked, arrived or not, party size. In the example restaurant, Friday and Saturday carry about eighty booked covers each and the no-show rate comes out at 8% — a bit over six covers a night, twelve or thirteen a week, roughly fifty a month.
Fifty covers a month at a $25 average check is $1,250 of sales that were planned for, prepped for and staffed for, and did not happen. What that is worth to your result is the contribution figure the budgeting course gave you — about half of it drops straight out of the bottom line — and it is comfortably more than most restaurants save in a month of arguing with suppliers. Rates vary a lot by concept and city; what does not vary is that the number is always bigger than the owner's guess.
Two refinements while you count. Separate the no-show from the late cancellation, because they have different fixes: someone who cancels at six is a table you can still sell, someone who cancels at eight-fifteen is a no-show with manners. And note the party size, because one table of eight is worth a dozen twos and changes what you are willing to do about it.
✅ What actually brings it down
In rough order of effect per effort, and the first one does most of the work.
- Confirm the day before. A message that can be answered with one tap — "see you tomorrow at 8, reply YES or tap here to cancel" — is the single most effective thing on this list, and it typically halves the rate. It also converts a silent no-show into a cancellation you can resell, which is the real win. How to write and automate those messages is the email marketing course's subject; that it happens is this one's.
- Take a real phone number and check it. Read it back on the call, or send the confirmation immediately so a wrong number bounces while you can still fix it. A booking without a working number is a booking you cannot rescue.
- Say the policy out loud at the moment of booking, in one friendly sentence: how long you hold the table, and by when you would like to know if plans change. Almost nobody objects, and it does more than a paragraph of terms nobody reads.
- Card guarantee for large parties and peak times. Not for a Tuesday two-top — for the group of eight on New Year's Eve. It is normal enough now that guests expect it, and the charge, if you ever apply it, should be smaller than the loss and explained before it is taken.
- Deposits for the nights that cannot be resold: holidays, private groups, tasting menus. A deposit that is credited against the bill is a booking that shows up.
- Make cancelling easy. This is counter-intuitive and it works: the easier it is to cancel, the more people cancel instead of vanishing — and a cancellation at four in the afternoon is a table you sell twice.
What does not work is being annoyed about it in public. Naming and shaming no-shows online reads to everybody else as a restaurant that is difficult, and the good customers are the ones who notice.
➕ Overbooking, honestly
The airline answer to an 8% no-show rate is to book 8% more people than you have seats, and it is worth understanding exactly why that is a worse idea in a fifty-seat dining room than at thirty thousand feet.
The arithmetic looks fine on average and terrible in the tail. Overbook two tables on a Friday and, most weeks, the no-shows cover it and you gain four covers. Then comes the night when everybody arrives: eight people standing in your entrance with a confirmed booking, a room with no seats, and no version of that conversation ends well. You have traded a modest, invisible gain on ordinary nights for a rare, extremely visible failure — and the visible one costs you a review, a group of guests and the staff's confidence at the door.
There is a middle version that is defensible: overbook only where you have somewhere to put people — a bar with real seats, a terrace, a section you can open — and only by one table. And there is a better version that almost always wins, which is the next topic: a waiting list turns the same no-show into a filled table without ever promising a seat you do not have.
⏳ The fifteen-minute rule, applied kindly
The last piece is what happens when somebody is late rather than absent. Decide the rule in advance, tell the guest at the moment of booking, and then apply it with judgement.
Fifteen minutes is the common standard, and the important part is not the number, it is that the guest heard it before they were late. After that, the table goes to the waiting list — but the booking does not simply evaporate: the good version is that the party is fitted in as soon as something opens, which is a completely different experience from being turned away by a rule.
Two exceptions worth building in. Call them before you release the table — a two-minute call recovers a surprising number, and the ones who are five minutes away will tell you so. And do not apply the rule to your regulars in a way that costs you the relationship over a table you were going to fill anyway; the customer data course knows who they are, and this is exactly what that knowledge is for.
