Just before Pennsylvania temporarily closed indoor dining at restaurants across the state on Friday night, one waitress received a large tip. Cheri Lyons, a server and bartender at Greystone Public House in Harrisburg, Pa., was working Friday night when a group of customers left her a $500 tip. "It just really touched my heart that people realize what we’re going through," Lyons told WHTM. "They told me 'Merry Christmas, keep your head up,'" she added.
