What must a customer do to process a return without a receipt?

To process a return without a receipt, the customer must utilize the Returns Management or Return button. This option typically indicates a digital or systematic method that the store has implemented to facilitate returns, especially when traditional proof of purchase, like a receipt, is not available.

The use of a specific returns management system allows the store to efficiently track returns and validate purchases, which helps in managing inventory and reducing losses from returns. By employing this method, customers can initiate the return process even when they lack a receipt, streamlining the overall experience for both the customer and the staff.

Other avenues, such as providing a valid ID or obtaining approval from a manager, might be part of the process in certain contexts but are not the primary means for executing such returns. Filling out a detailed return form has its place as well, but it is not necessary to initiate the return process using the returns management system. Thus, the Returns Management or Return button is the correct choice, as it represents the most immediate and efficient means for customers to return items without a receipt.
