Never was in Pook Soi Buakhao but learned that many of the girls are now working in Pook Soi 6. Information is from a good, direct source. Might be able to confirm it in 2 months, if the amount of girls in Pook Soi 6 really has significantly increased.
I guess i also experienced this when she left toothbrush, powder, lipstick such nipple-"pads" and her IPad in my room.
Even it was not agreed before, i met her the next night again. Obviously this "tactic" worked very well with me
But can`t say that i did not enjoy.
