no drinking allowed
A policy prohibiting beverage consumption in a defined area, with a possible exception for water.
A prohibition on drinking indicates that beverages may not be consumed within a particular structure, property, or area, with the possible exception of water. This prohibition is normally accompanied by a prohibition on carrying opened drink products, as the purpose of the policy is often to prevent messes and vermin associated with spilled beverages. It may also be applied in stores where drinks are sold, in order to streamline anti-theft measures.
Consumption is the defining activity, and water may be excepted by the specific policy. A restriction on carrying open drink containers can accompany the consumption rule.
No alcohol addresses alcoholic beverages specifically. No eating addresses food consumption, so either can be a separate rule in the same area.
