For the US military
folks, the US Uniform Code of Military Justice
s Public Display of Affection
, especially if it is between two
uniformed individuals. I remember getting chewed out by an Ensign
because I had my hand on my girlfriend's hand on a table. Guess he was jealous
, she was one of the few women who looked great in uniform.
There are always exceptions, though. The most notable one is when a ship returns from a deployment. There is more hugging, kissing and groping going on than a Roman orgy, but nobody really minds.
