This is true for fat people, but keep in mind that many people who use wheelchairs actually can walk for short periods of time, it just causes them extreme pain or they are in danger of some other medical mishap. Some people may not have their own wheelchairs because they are able to walk around the distance of their house, but may need one once they walk from the car into a store because they'll be walking or on their feet for longer than usual. I know this is about fatties, but I don't want people to generalize it outward to our thin friends who use wheelchairs. Lots of legitimate wheelchair users would be able to walk around enough to find accommodations.
