Once again, Cascade has nothing to do with this. But since you brought it up, Cascade does hold games, but when the game is clear, and the boss tells the clerk the new line, the clerk reads the new line, and the player bets the new line that the boss told the clerk to tell the player, Cascade never once told the player, "Just kidding, you can't really have that line we just told you". And if we mess up, we write the bet anyway.
