Register can be stressful, and returning items is one of them, especially online orders. Which is why you make sure everything is accounted for, let your manager or supervisor know you need help with the transaction and they can show you while they are scanning the items and receipts. The good part is the employees that will be around all the time, has your back as well as the management.
