Also I'm guessing that for a lot of boys "going to work" isn't the same chore that we in the west sometimes consider it and it's more actually a case of going and meeting up / hanging out with the same friends they'd be hanging out with anyway even if they weren't in "work" and when in "work" there's always then the added bonus of a farang perhaps buying them (all) a drink of two AND them maybe managing to get an off too if they're lucky - so closing the bar would simply be more of an inconvenience to that rather than a relaxing day off perhaps.
