Khamzat Chimaev vs Kamaru Usman

Khamzat Chimaev posted what appears to be a photo of Kamaru Usman working at a fast food restaurant. If Usman fought Chimaev who do you think would win. (Whether the photo posted by Khamzat was taken by Khamzat I do not know. If the photo is real Kamaru Usman is probably just doing some undercover celebrity thing… you know what I mean.)
