First canon onscreen appearance of eye glasses and toilets (here called a 'refresher') in Star Wars. However, the character Noa played by Wilford Brimley previously wore eye glasses in Ewoks: The Battle for Endor (1985), which is now 'legends' continuity.
In this episode especially, the Inventory Droid AP shows personality traits similar to Marvin the Paranoid Android from Hitchhikers Guide to the Galaxy.
The original premise for the episode had Killun Station be a revisit of Rishi Outpost from the Star Wars: The Clone Wars episode, "Rookies".
The droids' arguing includes quotes from "Anything you can do" from Irving Berlin's Annie Get Your Gun.
The Imperial Information Office control room and it's staff were inspired by the soulless control rooms in George Lucas first film, THX 1138 (1971)
