I've been in and out of the restaurant business, as a chef, owner, and manager. At every place I've worked there have been waitresses or bartenders using the venue to sell themselves - whether they're essentially callgirls, or just finding "boyfriends."
In posting about Vancouver, I was reminded of an incident with a really hot shot girl. A couple of us got her phone number, but one who gave her a ridiculously large tip wound up screwing her the next day - undoubtedly for several hundred, if not 1-2 thousand dollars more. He declined to state how much, but said she was worth every penny! She WAS hot.
Over the years I've overheard conversations of these deals being made.
Have any of you worked this angle?
