The First Potato Crisps
One day, a customer came to an expensive New York restaurant. He ordered chips for himself. A few minutes later he told the waiter that he did not like his chips, because they were too thick. The waiter was very angry. He went into the kitchen, took a potato, cut it into very thin slices, and put the slices into a pan of very hot oil. Then he came to the customer. To his surprise, the customer said that they were very tasty. They became the world’s first potato crisps.
