The Duluth News Tribune has the story of Dean Davidson, the man at Bridgeman's Restaurant who has been outed as the patron who paid other diners' bills.
His habit of secretly picking up the tab for strangers started on a whim and lasted about year, although he still does it on occasion, he tells the newspaper.
Davidson eats at Bridgeman's nearly every day and is also known for his daily trivia challenge at the eatery, the newspaper reported.
“Dean livens things up," one longtime waitress said.
Davidson's type of generosity is often called "pay it forward" – doing something nice for someone in hopes that they will do something kind for someone else. The concept has been a longtime theme in literature and was featured in the best-selling "Pay it Forward" novel by Catherine Ryan Hyde, which became a movie in 2000.
