You got me.
Except I don't live in Brighton, I live in North West London. I think that's far enough away for a midweek game to justify being 'smug' about how people really don't need to leave early. If I don't, then nor do 99% of the crowd.
My point is, I don't understand why people need to leave on 85 minutes. What's the point in going in the first place if you're going to miss the last 5 minutes? OK, if we're 3-0 up or 3-0 down I understand it, but not at 1-1! When we beat Sunderland last year I left at the final whistle (after extra time) and was still back home before midnight.
What annoys me is the people sprinting and pushing and shoving to get on the first train out, when they live in Brighton! Hang around for a beer after, you'll have a nice leisurely, quiet train journey home then.
Hoisted by MY own petard then! Sorry.
Everyone who chooses to leave early has their own reason though which is valid to them. I started work a 4.30 am today so getting back to Chichester at 10.30pm as I did (car) makes a massive difference to getting back at 11.30/12.00 if I hadnt left 5 minutes early. If I didnt have that choice I simply wouldnt have gone.
