False bookings, and the short internal note
A false booking is one made under somebody else's name or number, or sent as a prank, and it is a different thing entirely from a missed appointment.
The phrase sounds severe, so here is exactly what it covers and exactly what it does not. A booking is false where the name on it belongs to somebody else, where it arrived from a number or a profile that is not the sender's, where it was written as a prank, or where nobody answered the door and one of those three was also true.
Missing an appointment is not this
A guest who booked honestly under his own name and then did not open the door has made an ordinary cancellation, read on the notice scale like any other. Nothing about it is treated as dishonest and nothing further follows from it. The distinction matters, and it is drawn here rather than left to a judgement call afterwards.
The note, and what it holds
Where a booking does answer one of the tests, or where a visit ended because a limit was pushed at, a short note goes into an internal record. It holds the date, an account of what happened, and the name and number the booking arrived under. It is kept for twelve months and read by nobody outside the house.
What it is for
One question only: whether a later booking under that name is taken. It is not shared, not published, not sold, and not passed to anybody. Objecting to such a note, or asking for it to be put right or taken out, is described on the privacy page. Where the facts appear to describe a criminal offence, the police may be told. A guest who writes under his own name and is in the room when she knocks will never meet any part of this.
