In 1939 two brothers,Mac and Dick McDonald,started a drive-in restaurant in San Bernadino,California.They carefully chose a busy corner for their location.They had run their own businesses for years,first a theater,then a barbecue（烤肉）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 sold for fifteen cents.Cheese was another four cents.Their French fries and hamburgers had a remarkable uniformity（一致性）,for the brothers had developed a strict routine （程序）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 hundreds 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.
