Should sandwich numbers always be marked on the bottom of the sandwich?

The rationale behind marking sandwich numbers on the bottom of the sandwich can vary based on operational needs and clarity. However, the answer indicating that sandwich numbers should never be marked on the bottom of the sandwich reflects best practices for maintaining the integrity and presentation of the food.

When sandwiches are prepared, especially in a fast-paced environment like Jimmy John's, keeping the top of the sandwich visually appealing is crucial for customer satisfaction, as the top is typically what customers see when they receive their order. Additionally, marking on the bottom could potentially transfer ink or residue onto the bread, which could be unappetizing and affect the food's quality.

In contrast, the other options suggest scenarios where marking might be encouraged or required, which does not align with the standard practice of ensuring a clean and presentable product. For instance, marking for delivery orders could create confusion about the appearance of the sandwich, while suggesting marks only on large orders or always could complicate the workflow without offering significant benefits. Keeping sandwich numbers off the bottom helps streamline the service and maintain the quality of the food presented to customers.
