As they keep telling us on twitter - it was our Cup Final - apparently.
I guess you are towards the North end of the stadium because I am in the SWC, left my seat on the final whistle and made brisk progress to the station. Long queue but it was moving. Felt I was making good time to Brighton.
However, I was then stuck in the huge queue at Brighton until the 22:33 Littlehampton train and I would have had to have left my seat quite a bit earlier to have made an earlier train from Falmer to make the same train as you from Brighton.
I think where you sit in the stadium has a huge bearing on whether the journey home seems easy or not. Sat at the front row of the SWC means that leaving at the final whistle makes for quite a long journey home because by the time I get to the train queue, half of the North, East and West stands are already there! Having said that, it's a rare occasion that I would sacrifice the last 5-10 minutes of the game to avoid this - I just take it as part and parcel of where we sit.
