Jobs aren't supposed to discriminate in interviews, but they do. I've been to interviews where they see the cane and I can tell instantly that it's a no, purely because they think I'm incapable of moving around without it. As someone who uses a mobility aid part-time, and requires minimal accommodations, it's really annoying for folks to immediate brush off an applicant over something so minute. And like I said, they aren't SUPPOSED to, but it's also easy for them to say, "hey it's reasonable for us to want someone able-bodied because we need you to be able to move around and do stuff to this degree".
