A blackjack dealer and a player with a thirteen count in his hand were arguing about whether or not it was appropriate to tip the dealer.

The player said, "When I get bad cards, it's not the dealer's fault. Accordingly, when I get good cards, the dealer obviously had nothing to do with it so, why should I tip him?"
The dealer said, "When you eat out do you tip the waiter?"
"Yes."
"Well then, he serves you food, I'm serving you cards so you should tip me."
"Okay, but, the waiter gives me what I ask for. I'll take an eight."
