You sound like the type of punter who knows a chunk of the bar girls by name and thus now feels he is less likely to be a mark (less likely, l.e.s.s. likely, l.e.s.s. l.i.k.e.l.y), and also feels inclined to protect their reputations. But if you can tell me what sort of 'tourist' goes wandering into escape with their tour group badge on toting a camera around their neck I'll agree with you.
Ive been in HK over 20yrs too, never been rufied but I know lots of people - wanchai warriors, HK old hands - just yourself who have.
A bet a good chunk of the 'drunk sob stories' involve some sort of scam - I'm pretty sure others get rufied and never realise, they just have a massive inexplicable C.Card tab and figure they were drunk.
Ruff'ing has become a big problem in HK that the police do fuck all to solve - If you hang around there long enough, it'll happen to you too.
