Pissed drunk (and crude pissed drunk like the dude you described) pax on long flights and stewardesses in tight red miniskirts make a rather dangerous combination.

There was this recent case where a couple of DN pax felt up and pinched a stewardess (now that IT bought DN, DN crew dress in almost IT style uniforms - including short red skirts), got arrested on disembarking. And this on a short haul domestic flight where there's no booze.
