Step-by-step explanation:
To ensure our products are served at the highest level of quality possible, a 'best practice' might include several steps. Among them, wiping off the sides of the cups and dishes is important for presentation, using custard that has been made in the last hour ensures freshness, and always filling concretes and shakes to the very top of the cup guarantees customer satisfaction regarding quantity. Therefore, the correct answer should be D) All of the above.
High-level service particularly in the food industry not only looks at ingredients but also presentation and customer perception. Items such as take-out trays, foam packaging peanuts, CD cases, foam-walled drink cups, and egg cartons; are examples of products where quality can be monitored and ensured through careful practices like those mentioned.
