There was one from about 15 years ago down Beach Road that was drugged out but beautiful, I asked her "how much" she said "pay me how ever much you want, I dont care", I took her to my room and pretty much had my way with her, and I paid her 300 baht and a hug when she was on her way out the door. You don't see that anymore these days.
If they are I don't blame them especially with some of the ugly fat bastards they have to hop into bed with (just to survive for food )..there I said it too
All the working girls I've seen were healthy and clean. No drugs. Alcohol, yes, but no drugs. I go with the agencies and well-reviewed shops though, makes a difference, hence, the higher cost.
