My father was working in a post office in the early 80's. It was an unusually hot day with ~85°F inside. There were no fans available so it was crazy. Men weren't allowed to wear shorts, but dad came to work wearing shorts which covered his knees and a part of his shin, figuring he was fine. He wasn't, and his boss sent him home to change. He returned in his grandfather's bonjour from the late 19th century. Top hat and all. The boss kept asking if it wasn't a little hot in that suit but he said he was fine.
