Our CPO club was a veritable lion's den. If one of us dixie cup sailors stuck our head in there, it was liable to get bitten off. That was their refuge after putting up with us all day.
There even was an Acey-Ducey club for 1st and 2nd class petty officers, but when I went there after I made 2nd, it was "suggested" that the club was for career sailors, and that, since I was known to be longing for civilian life, I should go back to the EM club with the rest of the brats. Turns out that club was the refuge of the black shoe minority, awash in a sea of airedales. Black shoes weren't making rank anywhere near as fast as airedales, and the resentment was deep seated.
Cheers,
