WATERVILLE, Maine (AP) An anonymous customer at a Maine restaurant seemingly approved of the eatery’s service, leaving a $2,000 tip on a $48 bill.

Silver Street Tavern waitress Samantha Clark says the couple, who asked to remain anonymous, were friendly and easy to wait on, although noting there were a few mix-ups. The Waterville Morning-Sentinel reports the man later asked to speak with a manager and Clark says she feared he had a complaint.

Clark says she later learned the customer had left the large tip and instructed the manager to split it among the staff. Clark says the man is not a regular at the establishment and can’t think why he left such a generous tip.

Silver Street Tavern owner Charlie Giguere says “it’s a feel-good story.”
