The part where the Drew was trying to get the 1st director's finger prints off of the beer bottle... if you watch carefully, the director never actually holds the beer bottle with all of his fingers; his last finger (pinky) was curled up.
just because he didn't hold it with all his fingers at that point he had to have done it at some point...she was taking his empty bottle away and at some point while drinking that beer he had to have touched the bottle with all his fingers.
