Bit cynical, bkk?
What we want to avoid is confusing "hookers" with "poor girls". Even if you don't consider yourself rich, you are f'ing rich by Thai standards.
If a girl hooks up with someone who is *rich*, and *hot* and *everything she's ever dreamed of*, she's going to have emotions. Expecting her to be just looking for a hookup is ridiculous.
Bottom line, if you hook up with a girl, at a club, a bar, or wherever, and don't give her money, you are an *******.
If you make her your girlfriend, and don't give her *a lot more* money, you are the biggest ******* who ever lived.
Not that there's anything wrong with being an *******.
