Years ago, I was at Silver Star in Choctaw, Mississippi. There was a guy (appeared to be well-heeled) at my Blackjack table. He was so soused that he could hardly hold his head up. He kept hitting 13s against a 17 and dumb things like that.. I told the dealer that he shouldn't let that guy continue to play, and he kinda said under his voice, "they let him, I can't do anything"!

Obviously more money for the house, but I really thought that it was unethical, and I'm not sure, but maybe illegal.
