WASHINGTON — It was at Oregon's Timberline Lodge, later known as a setting in the horror movie "The Shining," where Patrick Doyle earned his first real paycheck.He was a busboy. The job didn't pay much. But Doyle quickly learned lessons that served him for years as he rose to become the CEO of Domino's, the pizza delivery giant:Show up on time, dress properly, treat customers well."I grew up a lot that summer," he says.As summer 2017 begins, America's teenagers are far less likely to be acquiring the kinds of experiences Doyle found so useful.
