Some stores seem to have too many and 1/2 are empty at any given time. OTOH, my 92 yo MIL lives with us and we have one for her. She gets around pretty good with a cane but she tires very fast. She gets out of the car takes off but if she had to walk in from many parking lots, she'd collapse. If it wasn't for handicap spots, we'd have to drop her off at the door then go park.
She's paid a lot of taxes in those years and her husband retired from the Air Force as a Chief Master Sgt. I think she's earned the right to park a little closer.
