What portion of the special order form does the customer receive?

The correct answer, which is the canary yellow copy, is given to the customer as it serves as their receipt for the special order. This copy is important because it contains all the details of the order, including the items requested, quantities, and any specific instructions. This allows the customer to have a reference for what they have ordered and to ensure that their expectations are met when they come to pick up their order. The canary yellow copy also helps streamline the process, making it easier for both the customer and the deli staff to communicate effectively regarding the order.

The other color copies serve different purposes, such as being retained by the deli for their records or being used for processing the order behind the scenes. The distinction in color coding is crucial in maintaining a well-organized order system.
