I think it was naive to leave early. As you say you've saved your money, so why not watch the full 90 mins? It was the slagging off of everyone else that didn't help matters.
Well done for coming back on though.
No thankfully everyone wouldn't leave, but I think the people that did go are entitled to question him as a "shit supporter". Maybe not quite so harshly but they made the effort to stay so why can't they have a pop at someone who buggered off when it wasn't going to plan?
He is still a stupid...
