There's no free lunches. But I could take a problem, make it arbitrarily harder, then take that arbitrary limit away. If someone thought they had to solve the harder problem, and found out they only have to solve the easier one, did they get a free lunch? This isn't meant to be allegorical or anything specific. I guess it's just an observation that sometimes your lunch can be cheaper than you thought.
