Continuity mistake: When Michael takes Katy (the purse lady) around the office, she worries about leaving her purses unguarded so while walking by Phyllis and Stanley's desk clump he asks Ryan to look after the purses, but Ryan says he can't because he's "installing File-Share on all the computers." Both Stanley and Phyllis are noticeably absent from the shot. Stanley's desk is empty and Ryan is sitting at Phyllis' desk. Michael and Katy take a few steps and walk into the kitchen area. In the background we can now see that both Stanley and Phyllis are now sitting at their desks and Ryan is nowhere in sight. There wasn't enough time for everyone to switch locations like that as only a moment had passed between the shots.
