Upon further review of the information you have provided, it is obvious that your Pizza has 8 slices of pepperoni. This may seem like a good deal, but in reality it is not. Pete's pizzas may only have 7 pieces of pepperoni, however is a Meat Trio which suggests that there are 3 different kinds of meat and not just 8 pieces of pepperoni like yours does. So with that said, Pete's Pizza is a better deal and he would have been more "robbed" had he bought your pizza.
I have to much time on my hands.
