" An equally unusual thing happened in 1953 when the McDonalds were designing their “golden arches” building. They wanted to lay it out in the most efficient way possible, placing windows and equipment so that each crew member’s job could be done with a minimum number of steps. Mac and Dick had a tennis court behind their house, and they got Art Bender and a couple of other operations people up there to draw out the whole floor plan with chalk, actual size, like a giant hopscotch.
