I am sure they disinfect them. But you could also bring some Lysol and do it yourself. I am embarrassed to say that I never thought of that! I, too, have a problem with pride. I am embarrassed to use a scooter because I think I look dorky. That is really a silly thing to think, too! But you know what? It is so much easier to use the aids than not to use them.
Btw: I got some cute outfits - skirts just above the knee, leggings, boots, cute tops, hats and scarves. Then it was hot there, so I bought a t-shirt. I stood by the letter A to have my picture taken and two other people took my picture, too!!! They either thought I was super cute or wanted a picture of a weird californian! The leggings with skirts worked out great because wearing them with dresses would have been uncomfortable in a wheelchair. I was still invisible in the wheelchair, but looking nice helped me feel better about it. I even posted pics on facebook.
Now I gotta act like a grown up. boo hoo
