Philadelphian gay rights activists stage first sit-in at Dewey's restaurant, 1965
Due to “a small group of rowdy teenagers,” the managers of the restaurant Dewey’s on 17th Street in Center City, Philadelphia decided to begin to refuse service to those patrons that were exhibiting “improper behavior.” This decision was expanded by some employees to mean “homosexuals and persons wearing non-conformist clothing," which, on April 25th, 1965, resulted in the refusal of service to over 150 people. Two teenage boys and one teenage girl proceeded to refuse to leave the premises when they were denied service.
