What the hell? I just played online there and was beating him up to the final whistle, and he quit and I didn't get the win.

I hate it when people quit, I know it's all choice but why choose. If you wanted a match and someone gives you a match then why quit if he beats you. I can't believe the amount of sore losers as well. I was Roma and he was Man United, he was winning one nil at half time then in the second half, scored 3 times. And I was about to say fair do's to making it to the final whistle and he quit.
This ever happened to any of you people?
