Would you charge a friend who isn't a blue more then?
I don't see the point you're making. You are actually losing money, to a stranger, who you're not sure is even a Blue?
There's a guy in the pub I drink, Manchester United season ticket holder, and he wont pass on his ticket for anything other thank the full ticket price. That's to friends/family/relatives/associates. And his reasoning is that (in his mind) it is a privilege to go and watch them play and that shouldn't be discounted in any way. So it's not about what he receives it is about what he believes people ought to pay to go and watch/experience United at Old Trafford. It's not my point of view, but I can certainly respect it as a standpoint.
