KillerDearlers:"It only works on this side of the table!" Players: But why?

Let's see if APs can give some good answers for the above referenced question. We all are familiar with these situations: Say Hilton Dealers had killed players with crazy good cards hands after hands. Players frequently asked Hilton dealers if dealers' lucks continued when they played blackjacks at Harrah's after work. The dealers always said that crazy lucks only worked on the dealer's side of the table, and that the crazy lucks in cards stopped mysteriously as soon as they're off duty. In fact one of the dealers lost his home to a casino because he had pushed his luck after work too many times. So guys, what are your 2 cents about "It only works on this side of the table?"
