Getting Gas

A man is driving down the freeway when he sees a sign that says: “Get gas and free sex here”. So obviously the guy was interested, so he stopped, filled up went inside to pay.
“Pick a number from 1 – 10 to get free sex.” said the cashier.
“Uh, okay, 3!” the man replied.
“Nope! Sorry play again”.
So the guy drove around for weeks always getting gas at the same place, because he wanted his free sex.
One day he was really ticked, “This has got to be rigged! I have never gotten the number to have free sex!” He screamed.
“Oh no! It’s not rigged, just ask your wife, she won 3 times last week alone!”
