Imagine a car dealership that provides every car buyer with a free car wash for as long as they own the car. You purchase a car, and along with the required paperwork you are given a free-car-wash certificate. The dealer tells you he has fully paid for all the car washes you will ever need, saying he believes that a clean car is the greatest way of advertising and promoting his dealership.

Several days later, you happen to drive down a muddy country road full of potholes and ruts. Later, you notice your car is covered with mud and decide to avail yourself of your free lifetime car wash. But before you have time to drive through the car wash, your friends inform you that you no longer have to go there. They tell you that your first car wash was all that was necessary. Any suggestion that you need another wash is not only wrong, but a lie.
