An "aisle" is a passageway between rows of seats, shelves, or other structures. It is commonly found in places like theaters, airplanes, and grocery stores. Aisles help people move easily through crowded areas and provide access to different sections. In a grocery store, aisles are lined with products, allowing shoppers to browse and select items. Each aisle is usually labeled to indicate the type of products available, such as dairy, snacks, or cleaning supplies. This organization helps customers find what they need quickly and efficiently.
