 Majority licenses are often specified by each state and localities that have laws and regulations in acquiring such a license.Otherwise, general categories that are covered under license laws include when and where liquor may be served, the amount that can be served, how much it may be served for, and to whom it may be served.Across the United States it is very common to have further specified protocols in restaurants such as limits on drinks per customer, zero discounts on drinks, and to have unfinished bottles of wine to remain in the restaurant.
