You often see young/fit-looking people queuing up for the tram back to Piccadilly. If more of these people were encouraged to walk back to the station it would make life easier for the FOC who can't walk as quickly.
It does have to be said though, the infrastructure around the stadium can't handle the current capacity, never mind an extended North Stand!
Personally, I do think that many supporters need to chill out a bit and stop rushing off after full-time. It's quite nice clapping the last player off, heading to City Square (or the new bar on SSL1), and having a pint. By the time you've finished, the queue at the met is usually manageable and the journey is more comfortable. I appreciate there are times when people need to rush home, but on most occasions, I'd rather chill and have a beer than get angry in a queue!
