Clue/Question: The garbage detail described the mess hall pickup as a . . .
Answer: HAUL MESS (or: MESS HAUL)
(Either way works, in my mind. I originally had MESS HAUL, but decided that would work better if the first word were MESSY, which it isn’t. Either way, it’s a mess and they’re hauling it away. Anybody think there is a definitive answer?) — YUR
(JT is the only one to chime in on this, and he was right! I guess it could only have gone either way in my warped brain.) — 🙂 YUR

YUR original answer –may be it. They –sometimes–like the same sound/same word order answer–as their story line.
So– a vote for Mess Haul.
Thanks
