I have been thinking about this for some time. Everytime you have a transaction with someone who works at a casino, even the gift shop lady, they say good luck. never have a nice day, cheers, goodbye, always good luck. Clearly they are encouraged to say this to every guest but i have always wondered why. I thinks its something like telling an actor to "break a leg" because saying good luck is supposedly bad luck in the theater. maybe thats what they are all doing to us, actually wishing bad luck upon us. hey, any advantage the house can get they will take.
