What could he have done? What 'consequence' can an unqualified Ensign really inflict on a Chief for saying something like that? He gave him a look and a sarcastic retort, but beyond that what is he supposed to do to not 'take it?'
No, it wasn't an isolated incident of overt disrespect from CPOs even toward qualified JOs, and really came to a boiling point at times.
A DH I served with poignantly said "I'd rather suck dick in prison than be an unqualified ensign on a submarine again."
Fucking have a spine and smash it. That's what he should've done.
