We have had over 25,000 before though, it can't be difficult to arrange safely. And why would you have a button and tell people not to click it? That's just daft.
There does seem to be about 200 less seats available than there was in our first stint in the Premier League, I think this is partly due to our digital ticket system now accurately counting everyone at the game, rather than assuming that all season ticket holder are there as we did previously. We're probably also wasting more seats for segregation than we did previously, I don't know why this is but I'll try to find out at the next SAG meeting.
I noticed the number of "tourists" to use a better word at the Liverpool game (some of them with Liverpool shirts on under their jackets (could see by the collars). I was unusually early to the game at Arsenal and there were loads there too. They were scattered around where I sit in E7 but one by one were moved by the actual seat occupier. They just seemed to sit anywhere and hope nobody would be there but they were all move on to their presumably "crapper" seats. I presume they buy their tickets when they go to general sale.
Didn't they have to take some seats out for the tv camera's I'm sure they did in the front row of West upper though not that many.
