re: Poker & How often do you get distracted when big tournaments players are playing very slowly
Don't let little things like this effect your game. Patience is a huge part of this game (I recommend reading "Zen and the Art of Poker" if you haven't). Also you can nicely chat and ask them to be more aware of what they are doing!
You should be focused on what's going on, why they are doing this, and what you are going to do. Don't let it hinder your performance but use this time to prepare and plan...
