The system of retailing operation used by supermarkets is self-service. This means that customers are able to select and purchase products on their own without the assistance of a salesperson. Supermarkets typically have a large selection of products displayed in aisles and shelves for customers to browse, and they often have pricing information and product details clearly marked for easy reference. This system allows for greater convenience and efficiency in the shopping experience, as customers can quickly find what they need and proceed to checkout. Additionally, it allows supermarkets to manage their inventory more effectively by minimizing the need for staff to constantly monitor and restock shelves.
