Both of them deserve an ass-kicking.
Guy with the bottle was a ****y. You shouldn't screw with people if you aren't prepared to stand up for yourself once you've provoked a reaction. This and other guys like him have filled Youtube videotaping their attention starved selves doing this stupid fake pee prank, and I for one am glad that someone responded such that he'll think twice about doing it again.
That said, the guy with the Ferrari was a douche. My first thought was that he strikes me as the type that bought his probably 12-14 year old 360 (clad in bargain basement silver) just the week before, having put everything he had toward an older used one because he can't afford a new one but still wanted to be able to tell people "I own a Ferrari" while implying no so subtly "I'm better than you" and reacted out of knowing he'd shot his wad and that one was all he had and all he ever would have.
Am I making it too obvious that I'm in a cynical, and not happy mood today...though after typing that, I do feel a bit better.
