A fountain drink dispenser is a machine commonly found in restaurants, fast food outlets, and convenience stores. It allows customers to serve themselves a variety of carbonated beverages, such as soda, iced tea, and lemonade. The dispenser typically features multiple drink options, which are stored in large containers and mixed with carbonated water to create the final product. Users simply press a button or pull a lever to dispense their chosen drink into a cup. Many dispensers also offer ice, allowing for a chilled beverage. This self-service system is popular due to its convenience and the ability to customize drink sizes and combinations.
