Shania Twain is a global superstar whose sold more than 75 million albums worldwide. But the Canadian-born singer's earlier years were rooted in a much more humble occupation. In addition to crafting her singing career at local dive bars, a young Eilleen Edwards spent her after-school hours asking hungry Canadians, "Would you like fries with that?" while working at McDonald's.

"I learned tons about the meaning of service there," Twain tells Time Magazine on her time under the golden arches. After high school, the Grammy Award-winning singer-songwriter also worked as a secretary and a resort revue singer to support her family after the untimely death of her parents.
