It really all exists in the world of 'politeness', a talent that many do not have and that even more have forgotten. You see it in all sports, when something fortunate happens at the expense of another; the tennis ball touching the top of the net before rolling over and plopping dead on the court winning the point. The snooker player who flukes a pot from an impossible angle. And in real life we see it all the time; the careless car driver who cuts you up just because he wasn't paying attention and didn't see you, as he politely gestures from his car seat through his rear view mirror!
I think you now get my point...... Except perhaps that stupid car driver, who doesn't politely apologise, but gets really angry as if it's all your fault and then brakes and try's to annoy you even more. In the world of poker, he is the one to say sorry to. The one who is going to get angry dos he is the only person in the world.
On the whole, it's nice to be polite, but don't do it in poker, cos it's not appreciated by the player who has just lost to a gut wrenching river that fell against his dead cert to win...... It's like kicking a man when he's down.
