First, let's not jump on the moderator of this message board for not allowing the bar to be directly named or given a "can't miss" hint. The libel laws in Thailand are such that it could place him in legal jeopardy.
I don't really think it matters as to which particular bar it was. It could happen in any bar. The main thing is to alert people that this sort of scam exists at all, so that people know what to look for.
I also agree with Hedda, in that I too have never understood why it should be more expensive to "off" someone who works at a bar, but is not a go-go dancer. If the logic behind it is that there are a lot more go-go dancers than there are waiters or doormen, then I don't see that as valid logic because they are rarely taken "off" in the first place. Also, any of the go-go boys are usually glad to serve drinks or handle the bill when waiters are not available. Also, how many boys are truly necessary to be outside shouting "Have BOY, sexy BOY. Welcome inside, Mister!"? If there is a true justification for higher "off" prices for them, I don't get it.
In any case, unfortunately more bars than just one have unscrupulous mama-sans who will try to scam an unsuspecting "farang" out of a few hundred baht when they see an opportunity. For that reason I think the incident itself is far more important than the particular bar in which it occurred.
