The Office Webisodes--Number 2: Phyllis
The investigation into the missing $3,000 begins with Oscar, Kevin, and Angela questioning Phyllis. Beforehand, Angela tells the documentarians that they are pretending to ask other people about the money but they still strongly suspect Michael. However, they have to go through the motions to make sure all their bases are covered.
As they question Phyllis, she admits that she once used the Dunder Mifflin corporate card to while out at a sales call. A heel broke on her shoe, and she ended up spending $14 to fix it. She does say that her boyfriend Bob Vance of Vance Refrigeration allows her to use a Vance Refrigeration credit card in case of emergencies, but Kevin seems to think that melting ice cream cake is the only situation that can be addressed with it.
In any event, the investigation continues. Who will be questioned next? My guess is Creed, since he has admitted to taking stuff before. We'll find out next time.
