Sarah ask the receptionist if Olympia's old office has been assigned. The receptionist says "yes" while her hands are on top of the desk, but immediately it cuts back to a pull of the camera, and then the receptionist is holding a pen.
When Sarah is down in the documents archives, talking with the receptionist, she places a box of binder clips on the desk and from the front angle the receptionist's arms are across on the desk. But immediately afterwards, the camera view is from behind the receptionist, her hand is touching the binder clips.
