How should customers store leftovers from Domino's sides?

Customers should store leftovers from Domino's sides in an airtight container in the refrigerator to maintain freshness and prevent spoilage. This method is effective because it minimizes exposure to air, which can lead to drying out, and helps control bacterial growth by keeping the food at a safe temperature. Storing in the refrigerator also allows the food to stay safe for consumption within a reasonable time frame, typically up to 3-4 days, depending on the food type.

While other storage methods might seem practical, they come with drawbacks. For instance, storing leftovers in a paper bag at room temperature is not advisable as it can encourage bacterial growth and spoilage. Keeping food in the original box in the freezer can lead to freezer burn and degrade quality, and wrapping in aluminum foil doesn't provide a complete seal against air, which could affect the taste and safety of the leftovers over time. Hence, using an airtight container in the refrigerator is the best option for preserving the quality and safety of the food.
