Amy's nametag says "Karen" in this episode.
At the end of every episode the card for the production company Spitzer Holding Company features a variety of items they specialize in. In this episode they list Diplomacy, Temps, and Vegan Hunting.
Amy's fake name tag for this episode reads "Karen," which is also a slang term used for an irrational, angry woman. Fittingly, the heat in the store makes Amy behave in an angry and irrational way.
While trying to fix the problem with the store's temperature, Glenn fumbles with the main computer heating system on the roof and accidentally changes the language on the monitor. Instead of English, everything is now shown in Greek.
Glenn has, for unknown reasons, a framed picture of himself in his office.
