You're welcome capcrunch. By the way, all the ladyboys tend to say they've got no clients. In the afternoons they're buying shoes, dresses and sending money back home. So all that money does come from somewhere.
A number of clients do tip them quite well in the bar. Some $10/$20 but there are some who give $50. And some customers pay rather well for services, I know of one who gave a laptop to a ladyboy on top of the usual fee.
Usually Fridays and Saturdays are their busy days, which why I always suggest looking for a bargain from Mondays to Thursdays.
Cheers all.
