What is a responsibility of a shift leader just before a meal begins?

A shift leader plays a critical role in ensuring the smooth operation of kitchen and service activities, especially right before a meal begins. Checking the cooks' box for leftovers or expired items is an essential responsibility as it directly impacts food safety and quality. This action helps to ensure that any items that are no longer fresh or safe for consumption are removed from the kitchen. It also aids in maintaining an organized workspace, ensuring that the staff only works with ingredients that are appropriate for the meal service. Prioritizing food safety is crucial in a dining environment, and this responsibility reinforces the importance of maintaining high standards for both staff and patrons.

The other options do not align with the immediate responsibilities necessary to prepare for a meal service. Reading the newspaper does not contribute to effective meal preparation, sending employees on breaks may disrupt the workflow right before service, and turning off the kitchen lights would be counterproductive as it would limit visibility and hinder meal preparation.
