Final answer:
Customers at venues with liquor licenses can consume their purchased alcohol on premises up to an hour after last call but cannot take it elsewhere unless certain conditions are met, such as for medicinal use or in specific international jurisdictions.
Step-by-step explanation:
Places with a Class A, B, or C liquor licence can allow customers to consume alcohol for up to one hour after the last call. However, customers must drink the liquor where they buy it unless certain exceptions apply. For example, during the Prohibition era, which lasted from 1920 to 1933, the manufacture, sale, and transportation of alcoholic beverages were illegal under the 18th Amendment of the U.S. Constitution. Although Prohibition was repealed in 1933 by the 21st Amendment, its history has influenced modern liquor laws, which may allow transportation of liquor under specific circumstances, such as if it's prescribed by a doctor for medicinal purposes or if it's for personal consumption in private by non-Muslims or visitors in some Middle Eastern countries.
Prohibition against alcohol has taken various forms throughout history and across the world, ranging from total bans to strict regulations and licensing systems. In the United States, complete prohibition was deemed ineffective due to widespread opposition, lack of enforcement, and the rise of organized crime, which capitalized on the illegal trade of alcohol.
