Mate, there is NOTHING to indicate he was "intoxicated," you are simply making that up. AS for bar asking him to pay, .. mate again, you assume far too much, there was no mention of him being asked to pay, why do you make things up, simply to justify your rediculous comment.
As you know, this is Thailand, if you query anything you risk retaliation. You are simply anti non Thais, for whatever reason. The fact is, he has been compensated, do you really think if the Thais were in the right he would have been... lol.
