It sounds to me like you don't belong at football games than, and your sofa at home is a better place. Who are you to expect others not to be able to go get a beer or a refreshment whenever they choose after paying over a hundred bucks at a game?? You remind me of those people who get upset because you want to stand at a game and not sit down the entire time.
When I go to football games I come and go as I please. I paid for my ticket, and leaving the row is not rude. When I go to a game, I can usually expect
* to have other fans coming and going in my aisle where i have to get up and let them by.
* I can expect to probably have beer spilled on me by the people sitting behind and above me. (Stuff like that happens at football games)
* I can expect to stand even if I don't want to, because the fans in front of me want to stand. (If I want to sit the entire time, than I can pony up the extra cash and buy myself a ticket in the front row.)
* I can expect to hear some really loud and obnoxious fan that yells the entire time with a weird voice.
* I can expect to sit next to some really fat guy whose arm takes up two arm rests. (It happens at times.)
If you can't handle or deal with these conditions, than going to an NFL football game is simply something you shouldn't partake in. There are like 75,000 fans at football games and they all paid for their ticket just like you did. Everyone doesn't want to be lazy and sit down the entire time for 3 hours. People drink beer and they need to use the restroom, they get hungry,(Everyone doesn't tailgate and eat before games), people sometimes have friends in other sections they visit, and people take smoke breaks from their seats. It's pretty inconsiderate to expect everyone to view and partake in their game experience the same way that you do.
