A weary traveller arrives at a rural railway station. To his delight, he sees exactly one taxi waiting there and asks the driver to take him to his destination. To his amazement, the cabdriver tells him: “I would love to take you there but cannot, I’m afraid”. “Why not?”, he asks, flabbergasted.
“There is a local bye-law that says a taxi has to be here at all times.” “But a taxi is here.” “Ah yes, but if I take you home, there would no longer be a taxi waiting here. That would violate the bye-law.” This is what can happen with statutory minimum requirements.
