Ahh, those peopel in front of you must have been first-borns. First-borns are known for believing that rules don't apply to them and rules arn't rules, they are just guidelines.

Sorry, I'm a middle child, so can't help with your dilemma. As much as it would realy annoy me, I would not say anything to anyone, but I would be really annoyed that someone was breaking the rules since I would neve even consider doing it myself.
