I wondered what would happen to the left-behinds, and it appears that anything goes, indeed. The big container re-appeared in position number one.
Inside it appear what looks like the base of a fan, and a toilet, along with podas. But no visible appliance or fencing from my previous post. So perhaps the people who delivered this container, being more than one and thus able to load those items into the container, did so, and took them away?
If so, a remarkable and encouraging display of initiative – kudos!
