According to a Facebook post by a user calling himself Rick Libertas Semper, a popular pizza chain refused to serve him because he was wearing four patches signifying his service as a U.S. Marine. According to his profile, he lives in Green Bay, Wis.

“I decided to go to Pizza Hut for their lunch buffet after work and was approached by the manager who came to tell me that for the safety of the patrons and staff they do not allow people in the restaurant wearing gang colors,” he wrote.

Of course, according to his account, the only ‘gang’ his colors represent is the Marine Corps.
