If a lot of other bars and entertainment venues pick up on DJ Station's idea and start doing the same thing, for some strange reason I don't see Thailand's powers-that-be letting them get away with it very long.
Also, it's kind of hard to circumvent a 9:00pm mandatory closing time.
The solution is so simple - let the bars and entertainment venues reopen normally without imposing all these silly rules. If another outbreak occurs and can be attributed to that, then close them. Thailand is not usually proactive, but if they're going to be proactive, at least do it in a way that makes some sense.
I knew somebody would try that one.
