I suppose economic decisions drive their life choices - sad really. But dont think its only tourists that visit the girly bars, maybe around the touristy, but outside that area the locals frequent a lot more. Lot of these girls have families to support. The girls that work for the bars etc do so 6 days a week and are not allowed to have boyfirends, if they get spotted with a fella on the day off, and the madam finds out they expect to be paid.
its a weird weird world
