While filming her TV series, "Mare of Easttown," Kate Winslet became obsessed with Wawa, a chain of American convenience stores. The British actress, 45, plays Delaware County, Pennsylvania, detective Mare Sheehan and to prep for the role, she would read local papers. "So, I subscribed to the Delco Times, so I would read this newspaper every day, and there would regularly be some article about Wawa," Winslet told the Los Angeles Times’ "Envelope" podcast.
