I find the crowd up in the ESU do react to stuff going on in the game (well the ones near me) but must admit that the early leavers piss me off no end....then again I see people leaving early in all parts of the ground. This isn't just an Amex thing though - see it happen in most premiership...
I don't recognise your description of the ESU to be honest. All the people around me shout at the ref , cheer, moan etc. etc. I think maybe it is the fact that it is the best view in the stadium (which you alluded to in your post) that slightly annoys those stuck high up in the WSU??
So your opinion of all of the 2,500 fans who sit in the ESU is based on one game? You must have been moving around that stand for most of the 90 minutes to get a true perspective of all the fans reactions to the game?
ESU are the best seats in the stadium for that reason. I started in the ESL and moved to the "Upper Library" when it opened. I had always decided that to face our magnificent west stand was the place to be. I stood on the East terrace at the Goldstone so I suppose I am an East side boy...
