Customers tend to return to businesses that they feel have treated them well and provided real value. In the information age, that can mean that customers consider themselves well-served even when they serve themselves. Check-in hotels and airports, grocery and hardware stores with self-service checkout, and restaurants with self-ordering are all instances of customers engaging in product or service self-ordering with a high degree of acceptance and satisfaction. The self-service customer appliance can provide customer service when, where, and how the customer chooses. If the self-service appliance is intuitive and easy to use, and the customer avoids waiting in line or enduring inconsistent service experiences from staff, then self-service can be a positive attribute that has been proven to promote long-term customer loyalty.
