In assigned seating concerts, people standing on their chairs in front of you. SO rude. Then everyone ends up having to stand on their chair just to see, and if the person in front would just get the fuck down, we could stand normally.

A little story that came to mind with this...I was at a popodyssey concert back in the day and I was on the floor, probably about 20th row. The people in front of me decided to stand on their chair and at the time I was a pretty timid 15 year old. I was pissed but I didn't do anything about it. The people behind me were rowdy and REALLY pissed. They decided to throw their beer on the people in front of me, only got them a little and splashed me completely with beer. I was beyond pissed. It was the one night I got to see my favorite group and those douche bags ruined it.
