Norwegians complaining/bragging about high alcohol prices is basically a meme. But it's true that prices have shaped the way we treat going out and partying. BYOB is fully expected at private parties unless anything else is announced. People rarely head out to nightclubs without being properly boozed up from a preparty at someones home. A store bought 0.5L beer could be as low as $2-$3, while a beer at a bar or a club is expected to be ~$12 at a very minimum, but typically slightly above $15.
