I had ankle surgery in my early 20s. Even after the boot came off I couldn't walk long on it. People were pretty nasty when I had to go shopping in those electric carts. If you look young and healthy they assume you don't really need it, if you're old and fat they assume you're just too lazy to walk. Even using a cane inspired ire.

That was just a temporary situation for me but it made me consider people who have to deal with that constantly. Sure, there's fakers and people taking advantage, but since we can't know without grilling a person about their medical history and we shouldn't do that to the legitimately differently abled people, it goes to reason you shouldn't do it to anyone. At least not over something as minor as a parking spot. Panhandling is a different story.
