Not me, they can discuss it. I just find it pointless because it wont change. If they say someone getting up in the game is disrespectful or they don't agree with it then I hope they never need a piss during the match, the disrespectful bastards!
I have left early myself, you find the people who openly have a go at the people leaving are complete hypocrites. They want these people to stay and support the team (whilst sitting in silence) when they then prefer to be distracted by people leaving and moaning at them instead of carrying on with their "support" At old Trafford in the last cup game I went to go toilet after about 70 minutes, bursting for a piss. Some bell end pulls my hood back and says where do I think I'm going and I best not be leaving early.
Either way people can do what they want, if you leave you have done nothing wrong if you stay you have done nothing wrong. Don't tell me to stay and I wont tell you to shut up. (not you personally)
