Just recalled one that was rather absurd. As mentioned I work at this art museum. Obivously we don't allow people to touch the artworks, since they're quite often pretty fragile.

So this one time, I walked into our golden age section and saw a blind man and his carer. The carer was guiding the mans hand across the surface of a 200 year old painting, while explaining what the painting portrayed. I walked up to them and with my kindest voice told them that it wasn't allowed to touch the painting.
"DISCRIMINATION!" the carer screamed, and then went on, in a threatening tone to explain to me that a blind person saw with his hands and not allowing him to touch things was robbing him of a right giving to everyone else. I couldn't do anything but apologize and direct them to the ticket office to get their money back if they wanted.
It's not that I don't respect disabled people, but come on. I'm sorry that you're blind, but the same rules apply to everyone, disabled or not.
