What portion of the sandwich needs to be covered by the folder liner?

The correct answer indicates that half of the sandwich needs to be covered by the folder liner. This requirement helps maintain the presentation and cleanliness of the food as well as ensures that the sandwich is adequately supported while being served. Covering half of the sandwich strikes a balance between visibility and protection. It allows customers to see the contents of the sandwich while still keeping parts of it contained, which is essential for maintaining its quality and preventing mess. This approach can enhance the overall dining experience by ensuring that the food is appealing and manageable.

In this context, options suggesting a smaller or larger portion, such as a quarter, three-quarters, or full coverage, do not meet the operational standards set for serving the sandwiches effectively. A quarter would not provide enough coverage for stability, while three-quarters may obstruct visibility and customer experience. Full coverage could detract from the presentation, making it less appetizing to the customer. Therefore, covering half aligns best with the goals of functionality and presentation in food service.
