However, it's the Poor Sport who doesn't always shake hands. The Poor Sport played bad and is now pissed at themselves and they are so upset, they don't want to shake hands with you. Probably because even though it was through their own bad play they lost, they incorrectly think their opponent got rolls or didn't deserve the win.
In reality, they are mad at themselves and yet they punish their opponents, the fans, the audience, and ultimately themselves by not acting professional.
Even Wikipedia says:
"Generally, it is considered inappropriate, if not outright insulting to reject a handshake without good reason."
What I don't get is, if the Poor Sport wins a match they shouldn't have, they will laugh and smile and shake your hand with no problem. If you beat the PS, God Forbid, then you are no longer treated with respect.
Good word: Respect.
I honestly feel when people do this, it hurts our sport.
It's like a golf pro not shaking hands with who he's been paired up with the last 18 holes; or the losing team of a football game heading to the locker room instead of walking cross the field of shame to shake hands; or a tennis player not shaking hands at the end of a match; you get the idea.
When the PS's do this, do they even realize what it does to their opponent? You are belittling your opponent. You are not giving them the respect they deserve for being your opponent.
And of course everyone talks about the PS when they do this. We sit on the sidelines and whisper, "Can you beleive they did that? How rude." Or, "There he goes again..."
This not only happens at weekly tournaments, it happens at big events, too. Just at the Texas Open one of the pros did this to her opponent. Many fans saw it, too. The PS walked away from the table without any acknowledgement.
The PS would have treated any opponent that way because she was upset she was outplayed (I'm guessing), but her opponent took it personal. It was uncalled for and disrespectful. And what kind of representation of the sport is a pro who walks off without shaking hands? In front of a large crowd no less?
Granted, we don't know what inner demons she was facing. Maybe she had an issue with the crowd, or something weird happened in her match. Who knows. However, even PS's need to act human to their fellow human beings and treat them with respect and offer a simple handshake!
I know we get angry at ourselves sometimes, or our opponents for whatever reason, but we (the non Poor Sport) would still shake hands with the Poor Sport EVERY TIME, even though if the reverse happened, they would just turn and walk away from the table briskly, rudely, and selfishly.
