Increasing petrol sales

A petrol station owner in Ludhiana was trying to increase his sales. So, he put up a sign that read, 'Free Sex with Fill-Up.'

Soon a Sardar pulled in, filled his tank and asked for his free sex. The owner told him to pick a number from 1 to 10. If he guessed correctly, he would get his free sex. the Sardar guessed 8, and the proprietor said, 'You were close. The number was 7. Sorry. No sex this time.'

A week later, the Sardar, along with his friend ,a Gujju, pulled in for another fill-up. Again he asked for his free sex. The proprietor again gave him the same story, and asked him to guess the correct number. the Sardar guessed 2 this time. The proprietor said, 'Sorry, it was 3. You were close, but no free sex this time.'

As they were driving away, the Gujju said to the Sardar, 'I think that game is rigged and he doesn't really give away free sex.'
he Sardar replied, 'No it ain't, . It's not rigged at all. My wife won twice last week.
