The name of the fortune telling machine is "What Does Grandma Say?"
The voice of the fortune telling machine sounds distinctly like Robbie the Robot from "Forbidden Planet (1956)", even to the clackety sounds after each statement. Robbie was played by actor Marvin Miller.
Even though the place is called Penny Arcade, the price of the fortune telling machine is handwritten as "5" above the slot. From the visible wear on the coin slot, it might once have been a penny.
