I had the bump thing happen a few times at the casino . I usaly blow it off to a drunk or some fat ass that can't control where there going or what ever. But I remember this one time I was at the Coushatta playing and there was an elderly black guy sitting at a machine next to me and he had his Wallet in his hand WITH a $1 bill sitting out on top of it and his thumb holding it down WHILE appearing to be sleeping/passed out? with his head slumped over toward the machines. I thought How odd .so when we got up to leave I gave his chair a good bump. I figured him for a cop .
