Ah, sanitation. I happen to work for a sanitation department IRL, and I find myself wondering how Finn's old workplace would compare. Harried supervisors running around checking on conditions and keeping an eye on their workers. Instructions coming down from On High that don't seem to make any sense. Squads in competition with each other over who can get more done (or get away with doing less). Stories about the disgusting or dangerous things the workers have picked up, or about the ridiculous things they've done on the job. That one guy who's on a sex offender list or suspected of a murder. The poor unfortunate in the office, fielding calls about how this-and-such location didn't get picked up and it needs to get done NOW. How does this sort of thing translate to the First Order?
Gen, sanitation detail in the First Order
