False bookings, and the note one leaves behind
A false booking is one placed under a name or a number that is not the guest's own, or sent as a joke, and a missed appointment on its own is not one.
The line is drawn around honesty rather than around outcome. Four things put a booking on the wrong side of it.
The four tests
A booking is a false booking if it was placed under a name that does not belong to the guest, if it came from a phone number or a profile owned by somebody else, if it was written as a joke, or if a no-show followed any one of those three. Nothing else qualifies.
What is not one
An appointment simply missed is not a false booking. A guest who booked honestly, gave their own name, and then fell asleep or lost track of the evening has made an ordinary cancellation, and it is read on the notice scale exactly like any other. Changing your mind is not dishonesty, and the house does not treat it as such.
The note, and what is in it
Where a booking does meet one of the four tests, or a visit is ended because a limit was pressed, the house writes a short internal note. It records the date, what happened, and the name and number the booking arrived under, and it is held for twelve months. It is read by nobody outside the house. It answers one question only: whether a further booking under that name is taken. How to object to a note, or ask for it to be corrected or removed, is explained on the privacy page, and where the facts point to a criminal offence the house may take the matter to the police.
A guest booking under their own name, in the room when she knocks, has nothing here to think about at all.
