Then he did something to change all that. And in a few weeks his restaurant was full of men with their lady friends. Whenever a gentleman came with a lady, a smiling waiter gave each of them a beautiful menu. The menu looked exactly the same on the outside, but there was a very important difference inside. The menu the man hold was the correct price for each dish and each wine, while the menu the lady hold was a much higher price.
