Surely this can’t be a realistic depiction of a wasteland when you still have huge boxes of Swiss pralinés just lying around:

Swiss chocolate (or fondue) next to a shack in the desert

It’s a bit sad that someone must have already eaten all the chocolate out of this particular one, since all it contained was unrelated medical items. But perhaps the previous owner simply finished off the chocolate and thought it would be a good idea to store first aid kits in the box instead of throwing it away. Resourceful!
