I HATE kids like that. Whenever (wherever) I see punks acting like that, I make a comment to my wife about how much they make me sick. She says to me "You were a kid once too, and you probably acted the same way."
Wasn't too long ago that I was a kid that age, and I can assure you, I would have NEVER acted like such a disrespectful, disgusting person.
I think Disney should post a rule board outside saying that anyone who acts disrespectful of others or doesn't follow thei rules, WILL be ejected from the park.
