Yeah, I hate that. http://www.greekchat.com/forums/ubb/tongue.gif I have a bad knee, from playing softball. (sprain, didn't take care of it, never healed.) So, when I sit for a long period of time, it's a bit of a strain. I make SURE to tell the managers, or ushers, when I go, because I HAVE to put my foot up on the seat. It never fails. The theatre can be totally empty, and someone HAS to sit in the seat directly in front of me, even when I tell them about my injury. I usually have to end up moving. http://www.greekchat.com/forums/ubb/tongue.gif Grr. People can be so... people like.

I hate it when people who come to the movie late expect you to get up and move down seats because they need an extra seat on the end. I mean, I understand that it's only polite to move down...but my theory is if you can't get there before or during the previews...go sit in the front.
I also hate teeny boppers. For some reason they're the loudest. My boyfriend and I went to see Tomb Raider and these girls were just obnoxiously loud and one kept stomping her foot. Then they left and I don't think they came back. I just wish people had the common sense to remember they're not alone when watching movies.
