I know someone with a very painful bone condition in their feet. They can walk, but if they can walk X feet to get something done instead of 2X feet, they will take the handicapped spot and save the walking. (They have the tag.)
Your view is that if they can walk the store, they should be made to walk the parking lot too. It kind of misses the whole point of giving them a spot close to the door, to make it easier for them to do their shopping.
I'll shut the fuck up now.
