I always walk past this butcher. And I always thought how stupid it was, to have an empty meat case.
And yet they seemed to be doing pretty good business. I would occasionally see a customer inside, and the butcher would be cutting up a rack of ribs. The place has all this fancy equipment inside, a gigantic walk-in freezer, and all that jazz. I would silently judge their life choices. Empty meat case! Really?
And then I actually read the sign. 개고기 = dog meat. Ha! Mystery solved.
