Euuh, I don]t understand everything as meant in English. First at all, like I said, I paid 1000 bath, NOT including the tuk-tuk fare. I give her more then the fare so she would certainly not have to pay part of the money she earned, everything else, how little, is extra.
Don't know what that has to do with age. I know that in Patong the girls try to have more then 1000 bath, but that is not my problem. Kata/Karon girls never ask more, and are happy. She worked in a back soi, off Bangla. In general, 1000 bath is ok, and if she wanted more, she had to ask. I know, some girls do not argue over it, but other ones are harder to convince. THEN it is your choice to take them or not.
I am not a cheap Charlie, but why pay more in Central, as you have the same thing but cheaper in Tesco. As long the girl has the going salary, I think you must not be over generous. Another guy will pay more, another less, at the end she will be happy.
But guys who try the freeride, do not have much of my sympathy.
