In bars, there is a bar fine..600 baht to 1000 just to buy the girl out of the bar. Short time is 2 hours ifor 3000 baht.. one shot.
Some girls will do a long time, 5000 baht, 2 shorts. They leave your hotel at around 6am. Last time I got my second shot in at around 2am. No complaints from her. I should have gone for more shots.
