People driving by a McDonald’s in Lynwood, California, might be baffled by an upside-down sign. The golden arches, typically standing as an M, have been flipped over to become a W. But this isn’t a bizarre prank or a careless mistake. The upside-down arches are in “celebration of women everywhere,” a McDonald’s representative told Business Insider in an email. Patricia Williams, the location’s franchisee, flipped her restaurant’s sign in honor of International Women’s Day.
