Etiquette refers to rules of behavior that make social interactions appropriate and polite. Dining involves more than just eating to satisfy hunger - it is an art. Proper etiquette during dining includes being punctual, greeting others, waiting to be seated and helped by the host, using utensils and napkins correctly, having good posture, passing food appropriately, excusing oneself politely if needed, and showing appreciation when others pay the bill. Both do's such as making small bites and chewing with your mouth closed, and don'ts like talking with food in your mouth should be followed for polite dining.
