Live folks go on tilt all the time. Played with a fella who was down, we were short handed on a limit table, but he was calling ATC. Easy to make money off of. We have a high hand bonus every 20 minutes, and he hit a straight flush with his ATC approach. We all say, there you go, money back. He takes a break from table, since straight flush when card room not full very hard to beat.
But, alas, someone beat it. Guy was still gone, I stated he was really going to be pissed when he came back. Pissed was a polite word for his reaction, chips thrown around room. When they tilt, they really tilt.
