I don't care, I don't clean out the halls, I rarely even clean out houses simply because I like to see them cluttered, I like it when it feels like someone lives there, an empty house removes that feeling. If I break in and rob someone (Rare, I almost never play thieves, i steal plenty but that's almost never my focus, just a thing I do on the side
) then I only grab a select few items that look valuable, such as some silverware, any gems I see and quality weapons or armor, everything else I leave. Unless the inhabitant is a bloody mess on the floor, then i strip the place clean, no need to trouble the new tenants with throwing out all the old stuff.
