Well that's dumb.
I've got a somewhat relevant anecdote here. I went to Germany with my dad in 2004 (I was 14 at the time), and one day we went into a video store that sold and rented video games and movies. I went over to the video game area and started looking at the games, particularly the shooter games and suchlike. In the US, I could look at the boxes with no issues whatsoever, since after all, it's just the boxes. But then, the store clerk comes up to me and tells me I can't look at them because I was too young.
Germany's really up-tight about violence and whatnot.
