Your Beer question. Well I never had an Officer order me to get them a beer,soda or whatever. I've had them ask me to grab them one or even send me on beer/pougie bait run. But never order me.
I did have a Lt Cdr order me to stop playing practical jokes on mt div officer once
( I had the poor guy so scared he almost didn't come to work )
