I think post-match celebrations are about respecting the opponent.
If I lost to him 7-6 in the third. I don't want to stand at the net for thirty seconds, waiting for him to shake my hand, while he jumps around bumping his chest like a guerilla.
I know it's nothing major, and like I said, there are many worse than him, but certainly earlier in his career he had more faults.
I think a lot of the celebrations happened after a hand-shake though? And, his handshakes could not be warmer, win or lose. And I mean, they (the winners) ALL celebrate, one way or another! That's what they play for! The 30 seconds is really an exaggeration here
. If one is to judge how one respects his opponent, it should be when they lose, I think. It's always easy to act nice when you win
