Incall Premises

[Trinity-Belle]

...people coming and going in a hotel is a daily thing, so most of the staff are on ignore mode...

Yea, and the fact that most of them are part timers so in reality it is unlikely that the same people will be manning reception when you leave as where there when you arrived!

Also... the staff in hotels are not ignorant. They do know what goes on. It is just accepted and ignored... part of life. Of course they can't be seen to be approving of it and if they get complaints then they'd have to do something about it, but so long as everyone is discreet they really aren't that bothered. Some of the hotels at the airports are practically brothels!
