Well obviously if a man has no arms they're not going to hire him as a cashier. >.> I used to work with a blind man and he cleaned the windows outside the theatre and was also VERY good at it. Also there, I worked with a mentally ill person and he was great. But their jobs are very limited of course. You can't have the blind man handle money or anything. So far I haven't complained about anyone with disabilties, they tend to do the job just as good as I would, well my first job was only busy work anyway.
