Before Vitale's invention, pizza deliveries were annoying because the cheese from the pizza would get stuck to the table, the steam from the hot pizza would make the box lid sag, and delivered pizzas took a long time to arrive. Additionally, toppings for the pizzas were expensive, adding to the frustration of waiting for a less than perfect pizza. Overall, the entire process of getting a pizza delivered was not as convenient or enjoyable as it is now with Vitale's invention.
