LOL, that’s too funny, all around the warning stickers!
Kind of reminds me of the time I was tasked with maintaining the coffee mess in our shop, and I protested because I wasn’t a coffee drinker, but they made me do it anyway.
So, I kept it neat and clean, and that involved cleaning the cups with aircraft cleaner. Clean as a whistle, they were.
Taste wasn’t an issue, because I did wash them thoroughly with detergent after that, but...they were upset, because some of them liked the coffee scum in the cups!
They didn’t make me do the coffee mess anymore after that!
I learned quite quickly to be cautious in both what and how you told a Sailor to do something.
Our navigator (airdale O5) on a CVN just despised Boatswain’s Mates for some reason. There was one in particular he always gave a tough time. Two or three times a watch he’d yell for Boats and tell him to get another cup of coffee, and to be sure to clean his mug out.
I was a young Deck DIVO and eventually asked Boats how he could be so calm, polite and accommodating to the NAV when he was always so nasty. Boats explained how he cleaned the cup in the head. Surprising how NAV never caught on to most of the bridge team smiling every time he took a sip.
