Michael C. Gabriele, who wrote "The History of Diners in New Jersey," told the Telegraph that "diners are the state's ultimate gathering places — at any moment, high school students, CEOs, construction workers, and tourists might be found at a counter chatting with the waitresses and line cooks."
During the civil rights movement, NPR reported, diners became a popular place for activists to hold "sit-ins" in restaurants that refused to seat Black people, despite many of them employing Black people to work there.
In 1964, Congress outlawed segregation in businesses such as theaters, restaurants, and hotels through the Civil Rights Act, but many diners in the South continued to segregate their establishments, afraid that seating Black people "would drive away white patrons," NPR reported.
