c) While working at the store a customer comes up to the register wanting to return a pair of pants. The customer doesn't have a receipt, but you can see that the tags are still on the pants. (3 points)

In this situation, the first step would be to check the store's return policy. If the policy allows for returns without a receipt, then the customer can be given store credit or a refund. If the policy does not allow for returns without a receipt, then the customer cannot be given a refund or store credit. In either case, it's important to be polite and helpful to the customer while explaining the store's policy. Additionally, if the pants were purchased in-store, it may be possible to look up the purchase using the customer's payment method or loyalty program information.
