As Kirby is talking to Mr. Moseby at the front desk, a woman in a red walks towards Kirby in the background. When Kirby goes to leave, the shot changes, and the woman is gone. With the direction she was walking towards, she would have still been seen going towards the exit next to Mr. Moseby.
While everyone is in the "boardroom", the same extras keep walking back and forth in the background outside the room.
