Free refill

Free refills occur when a drink's receptacle, usually that of a soft drink, tea or coffee, is allowed to be filled again by its purchaser, free of charge, after they have consumed the drink. Occasionally the glass or cup holding the drink is not reused, and the "refill" actually constitutes the acquisition of a second additional entirely new drink(s) for no added charge, usually of the same kind as the original, paid-for drink. Free refills are commonplace in the United States and Canada in traditional restaurants and fast food restaurants, while rarer in airports, cafés, or service stations. Around the world, the availability of free refills is typically scarce, but varies widely depending on the country and the type and specific ownership or chain of each establishment.
