A person walks through a narrow aisle in a convenience store, moving from the back of the store toward the front. Shelves of products line both sides of the aisle. A large blue cooler with "Pepsi" on the front sits on the left side of the aisle, next to a larger refrigerator case filled with an assortment of beverages and other items. The floor is white tile and the walls are painted orange. The ceiling is lit by fluorescent lights.
