My Dad never ever did this and I can never bring myself to do it either (even when we were 4-0 down to the JBs at home last year!)

And yet looking at the Amex and lots of premier league grounds like Old Trafford and The Emirates in particular, fans seem to be pretty happy to leave well before full time. Why?

I suppose that it is a long way back to Devon for Man Utd fans, before anyone says it.
