I read this in the "Grapevine Section" of the Pattaya Mail about 10 years ago.

A man walked into a gogo bar in pattaya and ask for a particular girl, finding out she was not there he learned she had moved to another bar not too far away so he made his way to the new bar and found her. After a few drinks he invites her back to his hotel where they spent the night making love.

In the morning the man gave her 10,000 baht and asked if he can see her that evening.

The girl not surprisingly readily agreed.

There followed a further night of spirited love making.

In the morning the man gave her another 10,000 baht and asked if she is available later that evening.

Again the girl happily agrees

The following morning another 10,000 baht is given.

Asked if they can meet again in the evening, the man says that he has some business to take care outside of Pattaya, but that he would return in a couple of days.

They agree to meet in two days time

On his return, another evening of love making ensued, and another 10,000 baht was exchanged.

Hoping for more, the girl asks if they could once again meet, and was disappointed to learn that the man would be flying home that evening.

"Where do you come from" asked the girl

"Germany" came the reply

"My sister lives in Germany" exclaimed the girl

"I know" say's the man "She asked me to give you 40,000 baht"

urban myth i think but still a good laugh
