There's a guy around here with a Purple Heart license plate and a handicap mirror hanger. He can walk, not well though. But he doesn't quite need a wheelchair. I'd pull out of a regular parking space to let him in if the handicap ones were filled.
Only half-joking, a good punishment for perfectly able people who park there would be to make them eligible to park there.
Most dont need them and many are just fat and lazy.
Now that I've noticed mostly applies to the electric scooters at Wal-Mart. I'd say at least half the time someone's riding it because she has a bad case of fatandlazyitis.
See my #29. That sign was posted before handicapped spots were enforced by law. Also consider who would be shopping at a PX and physically handicapped. I'd help.
