I HATE it when people blatantly violate the rules, like they don't apply to them. The "No Flash" one is really annoying. Or when you'd be instructed to move all the way over when seating at, say, the Country Bear Jamboree, and folks would plop down right in the middle. Drives me nuts. I become a rule-Nazi at DisneyLand 

My then 4yo asked me what that spelled. I was none to happy to have to try to explain that one!
