Final answer:
After guests leave, unused table settings must be cleared, leftover food correctly stored or disposed of, tableware prepared for washing, and waste separated for recycling or trash responsibly.
Step-by-step explanation:
After guests leave, unused or extra table settings should be appropriately cleared away, ensuring that any remaining food is disposed of responsibly or stored for later use. It is essential to handle the table settings carefully to prepare them for washing and future use. Any waste or garbage should be separated into compost, recycling, or trash as per local regulations to minimize environmental impact. The entire process helps maintain hygiene, order, and contributes to sustainability efforts by reducing waste.
