If you see someone in a chair that is only wearing socks or moccasins, it's a pointer to them needing the chair. Muscular dystrophy, MS, Spina Bifida and other problems can be hidden, but the ones who definitely need the chairs can't be denied them cos of the lazy buggers. The things cost mostly around $5000 or upward, so nobody is going to go out and buy one if they can help it, and the waiting list for replacements is quite long.
