What the hell is a soda fountain if not the dispenser that still exists in every fast food restaurant and bar in the world?
It’s probably about the artistic structures they were encased in, matching (or maybe not matching) the ambience of the place.
Even more evil would be to properly fry the sprouts, hence making them tasty. Then coating them with the chocolate camo.
The downside being that you would need to time it right to prevent the victim from getting stale stuff.
