Not knowing that someone is disabled is a defence for a complaint of disability discrimination. If it is known, then this defence cannot be used.

I'm not talking about benefit claims, i'm talking about everyday life eg if someone asks you to pass them something in a supermarket because they are disabled, there should be no questioning, making assumptions, stereotyping etc.

No proof is required, but someone minded to be unhelpful to the disabled should politely decline their request as opposed to making inappropriate comments like "You don't look disabled" or ask inappropriate questions relating to their disability.
