Here is a heads-up: 1)Live!Casino@Philly gets reallly sharp-eyes-in-the-sky. 2) A dealer made a mistake in a gamblier's favor. 3) The eyes caught the error. 4) The pitboss politely took back the chips overpaid. 5) Later the gambler got up and walked away a few purple-chips less. 6)The moral of the story is: grab the chips, walk away and cash out fast before the eyes catch onto the big error.
