Paxing on duty travel, I swapped seats with a passenger so they could have the window seat. Guy was huge, nice mullet, beard, dressed like a proper bogan. Starting the service, the cabin crew addressed him as “Captain xxxx”. He looked at me questioningly and I shrugged my shoulders, he then said “f$&kin A man, I’ll take that” and sat up a bit straighter with his new found title. Swear he didn’t stop smiling the whole flight.
