A customer named Charlie wanted immediate satisfaction with a rebate offer for a pair of garden shears. He claimed that More Power's local advertisement was not in sync with the rebate program that the manufacturer of the garden shears offered. More Power's store advertisement said the rebate offer was good during the week Charlie purchased the product. However, Charlie later learned that the nationwide rebate offer from the manufacturing company had expired the week before. Joe expressed confidence that the manufacturing company would honor the rebate when Charlie submitted it with the appropriate explanation.
