I second bigfatkilo. Years and years ago, I got a contract at a place out Liverpool way. It was the most depressing place you can work at, industrial area with nothing but warehouses and what looked like factories. Anyway, it was a 2 month contract so I thought what the heck might as well do some research for some action while I'm there. I always ended up getting home super late due to the long drive anyway.
So I found one of those $90 for 30 mins places. I still remember the place was like at the back of or attached to a warehouse looking building. The girls stayed in the rooms... I mean it looked like they literally lived in those rooms, had all their stuff in there. The system was each girl comes out to say hello and the punter at the front of the "queue" gets to choose first and so on.
I remember fucking a hot young Chinese girl there who had blonde long hair. Was a fantastic fuck, I was surprised... Way better than what I expected (I was frequenting 5* back then)!
