Back when I was just out of the hospital and gained a bit of weight (was only like 130, but still for me that was big) I had to use one of these damned things because walking physically hurt to the point I would almost be in tears after 5 min. Running errands was a bitch! I would have been a "small fat" then (thought I think by todays standards back then I was thin, wtf!) and even got a few accusing stares from people if I used a scooter and parked in the handicap zone. "You don't look disabled", bitch go away. If they aren't hamplanets I give them the benefit of the doubt for other issues, but if they're fat it's an instant condemnation.
