fine of 200'000 bath demanded by local police from a bar boy

Sounds like total nonsense.

Bars that facilitate prostitution are allowed to exist because they are a lucrative source of bribes.
I would imagine 50~80% of the staff at the gay bars are foreign and that a high proportion at the girly bars would also be foreign. This just gives an additional reason to collect bribes. However it doesn't mean the bar revenue is any higher, so there is not a bigger pot of money for the police to extort.
I doubt the police employ many people with a good grasp of basic economics.
