Really don't understand why someone doesn't do something like dump a tray full of soft drinks on him and make it look like an accident. Something they can't get in trouble for. Stage it, plan it out, where one guy does that, then another guy, then another guy does something else, then maybe have someone sit behind him that's more annoying than he is. Do the most annoying sound in the world thing right in his ear. What's he going to do? Call security? Just don't let him win by being able to play victim to physical violence.
