Final answer:
Inform guests about rotating chalkboard items upon seating, using a collaborative approach for listing and discussing these items in a small group setting.
Step-by-step explanation:
When you're informing your guests about the rotating chalkboard items, the best practice would be to share this information as soon as they are seated and before they make their selections. This way, they are informed of all the available options, including the special items that may not be part of the regular menu. To ensure everyone has a chance to input on the chalkboard items, you can use a collaborative approach by forming a small group. List five possible topics related to your rotation, leaving space under each for feedback. As papers or laptops are rotated every 10 minutes, everyone has the opportunity to comment, adding ideas and questions to each list. This strategy allows for comprehensive input and ensures that all group members contribute equally to the discussion of chalkboard items.
