Step-by-step explanation:
When serving appetizers or any food items in a restaurant or hospitality setting, it is essential to check back with the guests no more than five to ten minutes after the appetizers have been delivered. This practice ensures that any concerns regarding food temperature or quality are addressed in a timely manner, and it reflects good customer service. Considering food safety, it is also important to be mindful of the danger zone temperatures for perishable foods, which is between 4 and 60 degrees C (40 and 140 degrees F). Perishable foods left at these temperatures for more than two hours should indeed be thrown out to prevent the risk of foodborne illnesses.
