It's case old saying lost it's relevance. This is absolutely correct in developing countries which only has one main railway station or bus stand for the whole city or town. These establishments targeted one time customer who will never return in a year. Including metro is not valid or violation of the actual circumstance this saying originated. Including Mtro and even if still counting walkable distance of 100 m from the station almost covers the whole city. Doing this in Paris with more strict enforcement of food safety and quality isn't really going to validate.
