They put out this shelf and I want it, but I don’t want to seem strange? It would make a nice plant shelf, but it’s not something I can scurry away with, so people would see me while I carried it. Is that a bad thing to do?
EDIT: Never mind. Someone beat me to it. 😭
If you’re sure they don’t want it, take it.
If you aren’t sure, ask, if if they are there, and if they aren’t there, take it and ask later if they wanted it (return it if they did).
There’s no shame in re-using good or even repairable stuff: indeed, be proud.
