I wasn't under the assumption that they don't back off players, I was relating what one dealer told me. What impressed me about her story was the claim that the player who was barred was spreading $100 to $2000 and that it took a couple of hours of play at this level before he got the ax.

By the way, the game isn't a double exposure game. Its a face-up game, which is rare in double deckers. Such a game would improve your playing efficiency over the normal face-down hand held game.
