From Ben Schott, an examination of the inner workings, personnel, and lingo of casinos.
It is curious how irrational even experienced dealers and floor men can be, though inexplicable runs of luck may signal a flaw in security.
Supervisors have been known to perform a range of rituals to cool the action: Shaking salt behind players or under tables, turning the drop-box paddle around in its slot, standing on one leg, swapping out winning dice or cards-sometimes for replacements that have literally been chilled in a fridge. One shift manager places a folded surveillance photograph of a “lucky” player inside his shoe before walking the floor.
Craps is a hotbed of superstition. Pit bosses have been known to place seven ashtrays around a table, to spray paint the number seven on the table when changing the cloth and even to have “hot” tables moved an inch or so. Unscrupulous dealers might throw coins under the table to bring bad luck or find any excuse to touch the dice or brush against a shooter.
I still think it’s hilarious that casinos ban players for counting cards but it’s perfectly ok for the casinos to have the advantage in every single game they offer.
