When Roy is teaching Dorian how to assemble a Big Buzz Double Cheeseburger, he states that the correct order is to place 3 onions and then 3 pickles. However, when Dorain is making the burger for the first time, Roy states that you should put the pickles on before the onions.
After Dorian and Sally meet for the first time, we see the truck pulling away from the Burger Matic. The dog which had previously been in the bed of the truck, is missing.
