I seriously doubt this is going on much at high stakes tables. I think most of this is happening at micro tables and low limit tables, and especially freerolls. To me, a tournament that costs $1.10 to enter is just as serious a matter as a tourney that costs $110.00 to enter and I am going to play to the best of my ability in the little one just as much as I am in the big one, but some people have more money than they do sense, and "it's just a dollar" so they play like morons...
