Then he goes on to explain the mechanisms of his salary and their his offices practical operations. 
Later on, he has both of them make him tea. When he tastes that it's too warm, Fourth Kind gets angry and punches both of them while their Quirks are active. He tells them that the tea needs to impress their clients, and then says it's satisfying to hit the interns Quirk's.
