I'm convinced of it, and have observed this for quite some time while playing craps. I call it the Evil Knievel syndrome. People that used to watch him do his daredevil stunts would often comment that they were only watching to see if he could indeed jump over all those buses. But in reality, they wanted to see if he crashed. So how many of you have played craps and noticed that people will watch you as long as you are losing, but more times than not, when you get on a hot streak, they tend to walk away. I had the same thing happen on a trip this weekend. I hit 3 points and knocked out 6-7 come wagers along the way and the guy walked away in disgust. I'm guessing their mentality is if people are losing, it makes them feel better because they're not the dumb schmuck who just lost his bankroll. But if the shooter is winning, it annoys them because they aren't part of the action.
Can't stand people watching me shoot. They get the stink eye, sometimes even before they cause me to seven out! Bastards!
