SAL 9000 was the robot cashier of the school store last year. He was brought in by the mysterious Company to help solve the shoplifting problem the store had been having. Unfortunately SAL was shipped with a screw loose and, when activated, he proceeded to develop a strange identity complex that probably stemmed from too many viewings of 2001: A Space Odyssey. Because of the failure of that particular model, SAL was replaced with a more advanced machine. His current whereabouts are unknown.
