Continuity mistake: When Vera says "Meet Norm of the north" to Mr. Greene, Norm is standing on the floor away from the rug. The shot zooms in on him and takes a few steps forward without going anywhere near the rug. The shot cuts to him looking at the CCTV and stands still, but when he is on the CCTV in the next shot, he is suddenly standing on the rug. In the shot after that, he is standing on the opposite end of the rug.
