I took my young sons to the semi and they couldn't see because of the fans in front standing up. I asked the steward to ask those in front to sit down and he said there was nothing he could do!
That's because of selfish people like the original poster not caring that if he stands up everyone in the entire stand behind has to stand too.
I'll have my OAP Dad with me for this one and am fully expecting his day to be marred by the standing up. It's not the end of the world if everyone stands all game, like at the semi, it's when people alternate between the two that things get bad.
