Recall how Walgreens switched its focus from profit per store to profit per customer visit. Convenient locations are expensive, but by increasing profit per customer visit, Walgreens was able to increase convenience (nine stores in a mile!) and simultaneously increase profitability across its entire system. The standard metric of profit per store would have run contrary to the convenience concept. (The quickest way to increase profit per store is to decrease the number of stores and put them in less expensive locations. This would have destroyed the convenience concept.)
