@kempo...sorry, don't agree, whether your sitting in a tournament hall or playing on-line, your opponent deserves some respect. The medium of interaction shouldn't change the way you conduct yourself. By the way I can understand the analogy of playing a video game if ur playing a computer but not when it's a person.
Yep, it's not excusable just because you aren't sitting opposite each other.
A computer doesn't rudely time out, even if it was a video game.
