Well, I'm not sure about it. We are not talking about a restroom in a fancy restaurant here, but one of the night-life scene / disco's... there is always a lot of alcohol or even more in the picture as well.
If I just think back on my nightly tours through Amsterdam house parties etc. Very well could you get anywhere else a punch in return if you push people first ... now that this happens a bit faster
in Thailand if you push a Thai guy, well, looks like someone has not been properly briefed.
He might as well just have touched the Thai guys head softly 2 times and got the same result 5555
