We were dropping the trash and one requirement is that an officer be present. I was told to go get an officer. I found the Chief Engineer sitting in his room reading his Bible. I asked if he could come and be the required officer. He said, "sure."
When people saw the Chief Engineer behind me they mocked, "Hey! Couldn't you have gotten someone more senior?"
I didn't know that "officer" in this role meant to go find an Ensign or Lieutenant JG, not the officer who's 3rd in command of the whole boat. Folks got a lot of laughs out of that one.
Overall, though, life on a submarine is infinitely better than a surface ship. I served on a fast attack sub and a frigate. The people on a submarine help make life better because most of the jobs on a submarine are advanced and require clearances that people can't get if they're on drug waivers or dropped out of school.
