This is a strange analogy. A better picture of what food neutrality is would be a menu with identical prices for every meal, be it a three-store burger or a 1 oz of ketchup.
But it's easy to understand for people with a non-tech background. If they had made it more realistic (representing how net neutrality really affects people), it would've been much less entertaining and harder to understand. The analogy of no net neutrality=slow access to service is easy to get for customers and still somewhat true.
