Kid happened to notice first, before I did, that there are quite a few people around Koreatown (where the hotel we stayed in is situated) seemingly doing nothing. Moving boxes with one side to the other, conversing while the third one works, walking in and out of a building, or simply hauling containers on a small hand car around. We found the reason for the last; they are pop-up vendors that sell street food, and we caught them working on their setup.
