should have sticked to minding his own business My guess is that the tweeting guy, and the rest of the patrons, would have preferred if none of this had happened. They didn't choose to be witness to the conflict. It was the choice of that couple to thrust the situation on the rest of the diners. In that context, I can't see that the twitter guy is guilty of anything other than, maybe, poor taste.
