Ever see a job posting that says must be able to lift and carry 50/ 75/100lbs even though it's not really something that you would be doing every day at the job? Well, it's a loophole to not hire people with disabilities. I just learned about this while at a conference I went to for people with disabilities trying to find jobs. It's also why so many require you to have a driver's license even if it's not a job that requires driving.
Now as a disabled person, I always did have a feeling that employees were looking for a way to fuck people like me over but have a cover for it after all almost every job I've had gets really pissy when I pull out the state paperwork that I have proving my disability and rights to reasonable accommodations.
