Re: the hookers from "slipping their cards under your door"
No, seriously; kept having hookers push their cards under the door of my business hotel room in China.
The romantically names "Peoples Liberation Army Supply Depot and Hotel".
Another hotel had an even better way to get ALL the lights out; gently move one of the anglepoise lamps over the bed; the wiring would fuse and take out the breakers for the entire floor (also in China).
