How is that a sin? The guest leaves with a product that will make her happier in the long run. She'll remember that nice TM that was looking out for her best interests and will come back to a place that she thinks will care of her. She won't be returning the item, which means no payroll hours will be spent processing the return, no risk of financial loss from a product that may not be in good enough condition to be resold, and no payroll hours putting it back on the floor. Even if the guest declines to buy that day she'll still come back when ready to buy anything we carry because she believes she'll be treated right, in other words loyal customer base.
