The shot of the scalp and what I assumed was the tech in it made me think he was out for that. Either corporate espionage or a military person/black market arms dealer trying to find a way to make robot soldiers.
Maybe fucking with the one girl was to establish that they won't remember it was him that did it or something.
You'd still think the people running the shop would be on it though.

Unrelated, part of me thinks Geoffrey Wright might be a robot.
