When Linda comes back from lunch with Gayle she is wearing her apron, but in all other shots after this apart from when Bob says "Look, Gayle, I'm gonna level with you", she isn't wearing it.
After Gayle says "Oh my God", the burger of the day board changes from the Salvador Cauliflower Burger to what appears to be a chalk animal anus drawing.
When Louise gives Bob the rhino anus painting to hang up, it reverses when rotated unlike all the other paintings.
When Bob goes to confront Edith about the paintings at around 14:21 you can see a booth on the right side that appears to have been shrunk and when Bob turns around to walk out the door he steps on the booth.
When Bob is getting arrested the mics on the officers' shoulders switch from left to right then back again throughout the scene.
