Free Sex With Fill Up

In an attempt to increase sales, a gas station in rural Mississippi posted this sign for all of its potential customers to read. Free Sex With Fill Up is what the sign read. So after filling up his pick up truck, to the owner this customer said, "I filled up my truck. Time to pay up. I want my free sex for my fill up." The owner than told the customer to pick a number between 1 to 10. If the customer guessed the correct number, the free sex with fill up could then begin. The customer proceeded to pick the number 9. "You were close," the owner said, "it was 8 not 9. Maybe you'll have better luck the next time you fill up, but I'm sorry, no free sex this time. Over and over he'd fill up and always guess the wrong number. "Do you think that gas station game is rigged?" he asked a friend, "I often wonder." "No it's most definitely not rigged," his friend replied, "The owner is not a cheat. "I happen to know, because my own wife won three times in a row, and that was only last week."
