Poland is a part of 'East drinking culture', so we drink much and well.
Youngsters start drinking at 12-13, some one fifth of their parents even allow it.
You can go to pubs at 18, but in fact you can enter even if you are underaged, only there may exist some problems when you would want to buy alcohol, then it's as following: in bigger cities about 80% institutions (bars, pubs and shops) ask for id, while in smaller cities about 40%.
Most parents drink a beer now and then, some every day, and there is always vodka being drunk when there is some celebration, like new job, new flat, or birthday, or sometimes without an occasion;). No vine is drunk while having a meal.
Alcohol cannot be drunk in public areas, if caught: underaged should have some court problems, but they are usually freed, whilst an 18+ person is given a 100zł=25e fine.
Majority of teenagers drink beer sometimes or more often, cheap vine is also popular.
A bottle of vodka is a very commong gift.
Average costs:
cheap vine (0,7l): 0,9e
a can of beer (0,5l): 0,8e
beer in a pub (0,5l): 1-1,7e
a bottle of vodka (0,5l): 4-5e
Don't knwo other prices because i don't drink anything else
If you're caught extremely drunk (in bigger cities), lying on the ground or badly bangoing around, you are taken to a special place, don't know english word for this, for a night and you have to pay 100e for that.
