Yep, in Denmark, 'still-at-school-16-year-olds' can go into a supermarket or kiosk (newsagent) and legally buy alcohol. Providing it's less than 16.5% proof. Which would be most wines, beer and alcopops...
But - hic - you want to enjoy a cognac with your cigar? Sorry - you're going to have to wait until the grand old age of 18!
Skål! Med sodavand! (Cheers! With a soda!)
