Which of the following is NOT a rule for buffet service?

The correct answer, indicating that mixing different foods in one container is not a rule for buffet service, is valid due to the importance of food safety and allergen management. When different foods are combined in a single container, it increases the risk of cross-contamination, which can lead to foodborne illnesses. It also poses a problem for guests with food allergies or dietary restrictions, as they may not be able to identify which ingredients are present in a mixed dish. Maintaining separate containers for each food item helps ensure that the buffet remains safe and accommodating for all guests.

In buffet service, using clean utensils for each dish is essential to prevent contamination, posting reminders for guests helps reinforce hygiene practices, and ensuring proper temperature settings is crucial for food safety. Each of these practices contributes to a safe and enjoyable dining experience.
