/*
A shift belongs to a business, not to one of its shops.

Both halves of this used to demand an outlet, so the same two windows had to be
re-entered at every branch a tenant owns — which is how the third branch quietly
gets 07:00–15:30 and nobody notices until a cashier is filed under hours that do
not exist. A tenant that works 07:00–15:00 works those hours everywhere.

`locationid = 0` is now the ordinary case. A named outlet still works, because
one shop may genuinely run differently and those rows already exist.
