The topic tag line promised lots but didn't deliver (so I shall try to fulfil my own expectations of what I imagined I would read in such a thread).
I personally think there would be a big market for themed brothels and the pimps and madams are missing a trick here!
Picture this...
The cowboy western brothel straight out of a John Wayne cowboy movie. Enter it through a pair of swing-doors into a cowboy bar where they only sell whisky. Cowboys (actors) turn around to look at the newcomer. You could cut the atmosphere with a knife. Then a slut in one of those huge dresses invites you to sit down next to her - "not seen you here before cowboy", etc, etc. you can take her upstairs and nail her and the rest of the whores for a dollar.
Then there's the Total-Recall-themed brothel (not talking about the shitty remake, the one which helped sculpt my youth of course, and with Arnie in it - "get your ass to Mars!"). The whole seedy brothel is reconstructed from that one you remember from the movie - that cheesy strip-joint cum bar cum fuck-pad, and yes it was on Mars. Some of the prossies have a third tit. "You got a lot O' nerve showing your face around here", etc, etc. pick the girl you like and get down to business with her only to be interrupted mid-coitus by a gunfight between the authorities and the rebels supporting Quaid ("open your mind...", etc etc)
