Nineteen-year-old Lee J. Norris was employed by Burger Chef Systems as an assistant manager of one of its restaurants. On a day when he was in charge and change was needed, Mr. Norris left to get change but also decided to get Kentucky Fried Chicken at a nearby store for his lunch to take back to Burger Chef. The bank where Mr. Norris usually got change is 1.6 miles from Burger Chef, and the Kentucky Fried Chicken outlet is 2.5 miles from Burger Chef. After Mr. Norris left the bank and was on his way to the Kentucky Fried Chicken restaurant, he negligently injured Lee J. Govro in an accident. Is Burger Chef liable for the accident?
