Which of the following reflects a key duty during the shift leader's checklist before a meal?

The key duty during the shift leader's checklist before a meal includes ensuring that each food item is taste-tested. This practice is crucial because it guarantees the quality and safety of the food being served to customers. Taste testing allows the shift leader to confirm not only that the flavors and seasonings are appropriate but also that there are no issues with food that could affect customer satisfaction or health. Additionally, this step helps in identifying any adjustments that may be needed before serving, ensuring a consistently high standard in meal service.

In contrast, rushing to start meal service without preparations, eliminating leftover items without proper checks, and solely focusing on inventory counts neglect the essential elements of food safety, quality assurance, and overall meal preparation standards, which are vital for a successful dining experience.
