True enough. I've seen similar in China and the guys even bring expensive presents for the girls they visit often. Eventually the girls make private arrangements, as you say, when they are away from the clubs.

I went to one by accident in the rooftop bar at my hotel in Shanghai. The greeter girl at the elevator as I went to the bar was a Filipina who spoke Chinese, Japanese, Tagalog, and English. She insisted she was not one of those girls, but if I wanted to hire a room etc. I did hire a room, but only on the condition it was just me and her. We got on great. She got a little tipsy and agreed to play pool. Best out of three for her to come to my room later. I'm sure she let me win and she got the service elevator to my floor once the place closed.

We had a great time and formed a relationship for a while. I've written some slightly erotic pieces on here about it.
