That doesn't mean that it's empty, however. Sometimes, some of that Stuff
is justifiable and reasonable to hold on to, or it's stuff that you Really
Do Need To Have, but it doesn't quite belong in any of the other lockers.

"What's in _your_ [cleaned-out] locker?"
1) a transponder module meant to bring it into compliance with a deprecated standard
2) a storage device containing unauthorized open-source firmware for a non-critical component. It might be in violation of local patent law...
3) a box holding ID cards, all of the same crew member, all of them issued by different planetary governments.
