What is considered on premise vs off premise for alcohol?
In legal terms when you are not allowed to take beverages off-premise means that if you buy a opened bottle, a pint of beer, or a glass of liquor/cocktail, you cannot take the drink outside of the establishment (a club, bar, pub, or restaurant). This ensures that the patron and/or the establishment does not get into legal trouble regarding public intoxication (e.g. drinking alcohol out in the streets and getting drunk).
