What is the cost of adding a patty to a burger?

Adding a patty to a burger typically incurs a cost based on the restaurant's pricing structure. In this case, the cost is set at $1.50 for an additional patty. This price point might reflect the cost of the ingredients, preparation, and operational overhead associated with including more protein in the meal. It's important for servers to be familiar with such pricing details since they will need to communicate this information effectively to customers making modifications to their orders. Understanding the pricing helps maintain transparency and manage customer expectations about meal costs.
