Do you believe a contract has to be fair to be valid in this case below? You are a ski instructor at a resort near Whistler. After failing to make the last Winter Olympics, you got stuck teaching beginners at the local ski school. You are very bitter and charge high prices for your lessons, taking advantage rich kids who are first-time skiers by claiming they need several lessons before they can safely ski at Whistler. You make them sign contracts for packages of four lessons when they actually learn everything they need to know in one or two. You are now being hassled by a customer that you taught during spring break with a claim that you defrauded him. You maintain the contract is completely valid and binding because the law doesn't protect stupid consumers. Besides, you didn't hold a gun to anyone's head and force them to sign up for lessons. Frankly, you think the contract was valid and the customer was just too dumb to do any research and find out it was a bad deal.
