In my personal opinion the man does not know what he is talking about. I have a blue badge and I was requived to PROVE that I was disabled to the extent I cannot was a distance to shops etc. Only when my examination was concluded by a medical expert on behalf of ERC was I issued with my card, which I had to renew after three years, yes, same examination once again. I have researched so called face mask exemption cards, Doctors will not issue, a number of charities will issue for a monetary fee. Guess what, you do not require to provide proof of disability to obtain the card.
