 As operations vice president, Turner helped new franchisees get their stores up and running.He was constantly looking for new ways to perfect the McDonald's system, experimenting, for example, to determine the maximum number of hamburger patties one could stack in a box without squashing them and pointing out that seconds could be saved if McDonald's used buns that were presliced all the way through and were not stuck together in the package.Such attention to detail was one reason for the company's extraordinary success.
