Edit: Wikipedia page on drinking in public:
"In some countries, such as Norway,[1] Poland,[2] India and Sri Lanka[3][non-tertiary source needed], some states in the United States,[4] as well as Muslim-majority countries where alcohol is legal, public drinking is almost universally condemned or outlawed, while in other countries, such as Denmark, Portugal, Spain, Germany,[5][6] the United Kingdom, New Zealand, Japan, Finland, and China, public drinking is socially acceptable."
