As someone who hoards everything and doesn't like to bother with stealing things, I learned quickly that nobody in the galaxy cares about certain items. Disposable cups I get, but everyone is also just fine with you taking all their pens, styluses, notepads, notebooks, folders, plants, pots, pans, and that one desk toy that looks like a bunch of balls stuck together.
I've actually never seen an empty beer bottle that was owned before, but I have seen almost identical full bottles right next to them that are, making it easy to steal accidentally if you're not paying attention.
