When Jonah approaches Amy in just an apron, a holdall can be seen behind her, branded with the word Oceanic. Oceanic is a generic airline which film makers use so that they don't incriminate any specific airline. For example, it's the airline in Lost (2004).
The sleeping woman featured in the mural that Amy and Jonah are painting over is Nichole Bloom, who plays Cheyenne.
A muzak version of "Maneater" is playing in the store while Amy and Jonah are painting over a mural of the Cloud 9 spokesman-turned-cannibal.
Most of the urine samples on Dina's tray are a dark orange color, rather than being yellow or clearish. While this is not necessarily an error, it would indicate that a large number of the employees in the store are dangerously dehydrated or otherwise ill.
Amy wears a different name tag in each episode. At the beginning of this episode her name tag says "Ella" and after the opening credits her name tag changes to "Heidi".
