Self-service is a form of service found mainly in cafeterias. In this type of service, customers usually select and serve their food themselves from a variety of dishes that are laid out in a line or a buffet-style arrangement. This allows for greater flexibility and speed in service, as well as giving customers more control over the portions and types of food they wish to consume. Self-service is also often associated with lower prices and a more casual dining atmosphere, making it a popular choice for many people.
