I had the same problem as in the middle airplane seat. A normal sized guy sat next to me, with his sweatpants side pockets loaded with stuff. So now you spend the whole game with his pocket of stuff pushing against your leg, he probably doesn't even realize it. What are you supposed to do? If you mention it bothers you, do you end up getting slugged?
You just have to hope there's an open seat and move.
The guy in front of me constantly leaned back on my knees the whole game too. Just oblivious...
One thing I don't understand is why they keep it so cold in the dome. Is this just in the 300's where you have a cold breeze on the back of your head the whole game? It's a beautiful 70s outside, and the dome is like low 60s with a breeze. It's too warm outside for a jacket, but you need it inside and it will still be cold. It really ruins the idea of having a domed environment.
