Home Depot has healthy people using theirs all the time. Too lazy to walk around. Their selfishness sometimes keeps a person who actually needs one from using the service.
I am fairly young to have arthritis, there are days I would give anything to use one and probably should. I have given up shopping malls and big stores due to pain. I am sure that I look way to young to be on those kinds of things. The day I cave in and use one I am sure someone will say much the same about me.
