I think the OP means the constant stream of people desperate to relieve themselves or get to the bar, and the pointless drone from horns.
I was on the end of a row and spent most of the game either standing up for people or craning my neck to see round people going to the exit.
That said, I'm not going to complain. I'd rather stadiums felt at ease enough to allow alcohol and horns at seats. I had a couple of beers at my seat and enjoyed them thoroughly.
Horns, on the other hand...
