Continuity: In the episode, 'Backpack', when Zoey and her friends are confronting Stacy, the shot goes to behind Stacy and Nicole says, "You're not closed." At this point, the side of the sign on the table facing Stacy is blank. Then, after Michael tells Stacy that she can't close a table, Stacy flips the triangular sign so that the side that was just facing her (the blank side) is now facing out to Zoey and her friends and has the word 'closed' on it.
