In Thailand, it is no longer fashionable for top girls (tallish, sexy, beautiful) to want to work in prostitution. If you want to see stunners in Thailand, go look at the staff at your local bank, hospital or shopping mall.
And I'm not even talking about bar-fines, lady-drinks, Asians-only, coyotes and other trickeries and downsides that characterise Thailand night-life these days.
