A petrol station owner wants to sell more petrol in a small village. He writes on a board, “Free sex for a full tank.”
Many people come to the petrol station. One of the first people is Hugo. When his tank is full, he asks for free sex.
The owner tells him, “Tell me a number from 1 to 10.”
Hugo says 8.
The owner says, “The number is 7. Sorry. No sex this time.”
The next week Hugo comes with his friend Augustin. When Hugo’s tank is full, he asks again for free sex.
The owner wants to hear the correct number again. Hugo says 2 this time.
The owner says, “Sorry, it is 3. No sex today.”
Hugo is angry and he tells his friend Augustin, “I think it is a marketing trick and there is no free sex.”
His friend Augustin says, “No, it isn’t a trick. My wife had free sex twice last week.”
