Yeah. I've known people who used someone else's pass to park a little closer.
Some people are not obviously disabled. My kids' neurologist offered one to me because she was terrified that Youngest would run out in the street. I didn't feel right about it, so I declined her offer. I carried him (biting, kicking, pulling my hair, and screaming!) or put him in a stroller until He would hold a hand reasonably well. In hindsight I think I probably should have accepted the pass.
