Urgh, "low-alcohol " or not, I don't understand why they'd let some middle school kids just walk up and take a cup of sake. I don't like drinking, and I especially don't like underage drinking. That was something I never expected in this Manga, but that's Japanese culture for you. It's attitude regarding alcohol is probably I dislike most about Japan.
Man, I dragged that on instead of focusing on the nicer parts of this chapter, didn't I?
