I definitely get frustrated when players let the timer run every single hand. I know sometimes it can be a strategic move to run the timer about but not every one. I am such an impatient person it really gets to me but I never let it affect my game play or decisions.
If it happens every hand than I will leave the table. Not worth the aggravation.I hate slowness at the table. But I respect the time the villain has to play. I don't complain!
Was it close to making the money? I usually do that if Im really close to making the money.Its a strategy a lot of people use. Now if they are going slow like that at the beginning it would piss me off. Really no excuse or reason for it then. But like you say you have to deal with it , there is nothing you can do about it. And it sucks for sure...I was in a tourney once where a player ran the clock out every single hand and then came back right away. Every hand!! I sat at the same table with them for over 1.5 hours. Nothing I could say would get them to stop.
