My concern is that after the game I like to stay behind for a pint (Northstand) to let the train queues disappear. But at the same time, fans from other stands come flooding in as well so you spend as much time queueing at the bar as you would in the train queue, defeating the object. Where do those mobile Harveys kiosks go after the match? A few of those in the concourse would cure the problem.
This is a real problem. I sit in WSL and drink there before the game but often migrate to the North for a couple of pints after the game. Sadly on Monday this was only 1 pint as the time I would have spent drinking the other one was spent queuing. It did seem particularly slow.
