Cor I'm pretty sure our receptionist does this. She's the size of a house, probably litterally, and everytiem there's cake in the office tries to justify it whilst grabbing her 2nd/3rd/4th slice. If she wants it, eat it. As long as she don't break the drive on the way home I don't care (well that and as long as I get some). She doesn't need to tell me her life story about why she's allowed a slice of bloody cake!
In fact I might send this around the offiec tomorrow hoping she gets it
