If a sandwich is served by itself, should it be marked before handing it to the customer?

The correct answer is that a sandwich should not be marked before handing it to the customer when it is served by itself. This practice is based on efficiency and simplicity in service. When a sandwich is presented alone, there is typically no need for additional identification or marking since the sandwich itself can be easily identified by the customer.

In situations where a sandwich is served with sides or other complementary items, it may make more sense to mark it for clarity. However, when it stands alone, marking it might be unnecessary and can slow down the service process. The focus is on providing a quick and streamlined experience for customers, ensuring that their orders are served promptly without adding extra steps that do not enhance understanding or service quality.

This approach helps in maintaining an efficient workflow, particularly in a busy setting, where quick service can improve customer satisfaction.
