In 1939 two brothers, Mac and Dick McDonald, started a drive-in restaurant in San Bernardino, California. They carefully chose a busy corner for their location. They had run their own businesses for years, first a theater, then a barbecue restaurant, then another drive-in. But in their new operation, they offered a new, shortened menu: French fries, hamburgers, and sodas. To this small selection they added one new idea: quick service,no waiters or waitresses, and no tips. Their hamburgers were sold for fifteen cents. Cheese was another four cents. Their French fries and hamburgers had a remarkable uniformity , for the brothers had developed a strict routine for the preparation of their food, and they insisted on their cooks' sticking to their routine. Their new drive-in became surprisingly popular, particularly for lunch. People drove up by the hundred during the busy noontime. The self-service restaurant was so popular that the brothers had allowed ten copies of their restaurant to be opened. They were content with this modest success until they met Ray Kroc. Kroc was a salesman who met the McDonald brothers in 1954 when he was selling milkshake-mixing machines. He quickly saw the special attraction of the brothers' fast-food restaurants and bought the right to franchise other copies of their restaurants. The agreement included the right to duplicate  the menu, the equipment, even their red and white buildings the golden arches . Today McDonald's is really a household name. In 1976, McDonald's had over$1 billion in total sales. Its first twenty-two years is one of the most surprising successes in modern American business history. Mac and Dick managed all of the following business except   _  .
