A note for the future (Steam release and its non-Steam graphic-poorer kin) is seemingly that rooms-as-zones will stop the "single item of furniture as a nexus" of the current version.
Though you've made me think, now, as I've pretty much ignored Stands and Racks (except as a choice of Barrack definition, with no other use, or as items required to fulfil a higher Noble's room-demands as - as far as I could ever tell - just passive additional decor like statues).
I don't think I ever put containers in barracks (or overlap their extents, anyway), but I may put food'n'drink stockpiles[1] there (flasks for military but no carried food, for the mentioned reasons) and never noticed the bad thoughts from cupless drinking, but maybe I just never had it acute enough to be obvious/they satisfy themselves enough whilst off-duty and sitting in civilian rooms dedicated to the tinkling of tankards...
[1] Perhaps as part of a general policy of adding 'branch' dining areas in the increasing reaches of the fort, with staging-stockpiles to
try to impart some resupply efficiency in shuffling such things out from the supplying workshops and the central commissary/refectory 'grand hall' that I don't expect the more distance-working dwarves to retrace to. But as I tend not to set up the obvious "take from/give to" settings that I think is best, it's possible that I'm actually encoraging all kinds of counterfactural cargo-hauling as branch-end stockpile items get chosen to back-supply nodes closer to the manufacturary at some point. This is
not one of the many aspects that I actively micromanage to death.
