The number belongs to the cashier

A regular who messages a small restaurant to order does not have the restaurant's number. She has the number of whoever answered the first time.

The proof arrives the day that person leaves. The replacement picks up the same handset, sends a polite note explaining that they have taken over, and the thread goes quiet. The data transferred perfectly. Every order, every name, every note about the sauce on the side. The permission did not transfer at all, because it was never given to a business. It was given to somebody who knew her order.

What happens next is a purchase. A system, a shared inbox, a number registered to the company, a plan to import the history. All sensible, all worth doing, and none of it touches the thing that broke. A permission is not a record. It is one person agreeing to be interrupted by another person, and no import moves that.

The decision nobody makes on purpose is whose name the customer is allowed to know.

There are two honest answers. Either the business is the name, in which case nobody signs a message, everybody answers in one voice, and the relationship is deliberately thinner and deliberately portable. Or a person is the name, in which case that person is an asset with a salary, a successor and a reason to stay, and the handover is designed years before anybody needs it.

Most small operators have chosen the second without knowing they chose anything, and pay for it with none of the retention that would make it work.

The most valuable list in the business belongs to whoever answered first, and that was a decision. It was simply not made by anyone.
