On the Caribbean Princess, formal night #2, western Caribbean cruise from Houston Bayport, back in 2014, there was a guy at our shared table in camouflage outfit, short pants, army boots, and didn't take off his also camouflaged hat for dinner, Further more, he ordered 4x the lobster successively.
Restaurant stuff let him in, but asked us at the table if it was ok.
It was a remarkable evening. 😄
