You work at a sporting goods store. One day a customer arrives to purchase gear for a winter camping trip. Specifically, she wants a sleeping bag that is rated to -30C and a parka that has an equally strong temperature rating. You find a parka that is rated to -28C on the label, but you are certain she will be warm enough in this coat. The warmest sleeping bag that you have in stock does not have a specific rating, but other winter campers purchase this bag and report that it is very warm. Write a script outlining how you would handle this customers concerns about these products in an ethical way.
