Hi XQ,
despite REM making brill noise's, there can be no excuse, or tolerance for this type of behavour, normal people who are passengers in commercial a/c are nervouse of everything, for some pea brained jerk to start throwing his weight, and I belive food and drink, about, would possibly frighten the wits out of some fellow passengers, the man has shown he is a JERK, and he should spend some time in a room with no door handle on his side, to reflect on how to treat others. A fine, to suit his pocket would also show him he was wrong, but you watch, very little will happen to him!
