The incoming CEO of US supermarket group Shaw's says that tailoring stores to the areas they serve is vital to their success. "We don't want to be one-size-fits-all," said Gannon, who became Shaw's president and chief operating officer in May. "We want to do a better job than anyone in the marketplace, by tailoring the products and the overall store to the customer needs. We think we've gotten pretty good at that over the past three to four years. In fact, very good."
