Just had a thought............. back when I was younger, we used to be able to make some extra money by showing up early saturday morning after a game and cleaning the stadium. We would pick up trash, on and under the stands.... empty the trashcans, pick up all the tape etc on the field, tuck the purple and white feathers that fell off the Indian Spirit in our jeans to take home. It wasn't much fun at all, quite nasty really, but it was some pocket money.
So - if these kids are disruptive and caught, they are REQUIRED to show up Saturday morning and CLEAN UP THE MESS at no cost. If the parents are worth a damn, they will have their "angel" there first thing am. I know I would and I'd probably make them do MORE when they got home. I might make an impression.
If there are any politically correct responses to this........... save em, because if I agreed with you, we would both be wrong. ;D I'm not PC at all - personally, the entitlement these kids have, is part of the problem.
