Cafeteria dispensers are machines that dispense food and beverages in cafeterias. They come in a variety of shapes and sizes, but the most common type is an urn, which is a four-letter word. URNS are typically used to store and dispense hot beverages such as coffee, tea, and hot chocolate. They are also used to store and dispense cold beverages such as soda and juice. URNS are usually made of stainless steel or plastic and have a spigot at the bottom for easy dispensing.
