Blimey, I disagree with ALL of that. I loved the stadium. Never understand the need to stuff one's face at a footie match. I go to watch the footie. No drinks outside? And?? Poor service inside? No complaints here.
Walked round the houses to get to the away end? What, you had to walk. They didn't provide you with those transporters you see at airports: do you get dropped off at your entrance at the Amex?
As for the criminal like checks on tickets. What they done with mine is look at it and say "in you go".
Don't worry, be happy.
Just shows us then. You were lucky.
