I’m disabled. Fairly obvious disability as I use a wheelchair. But from the drivers’ seat I don’t look disabled. Can’t tell you how many times I’ve driven into a disabled spot and before I’ve even got the car door open, some busybody has rushed over to point out it’s a disabled space.
The most batshit occasion was when a very angry woman demanded to see my badge, saying she wanted to check that the photo (on the reverse so would have to have taken it out of the holder) was actually me. I pointed out that unless she was a police officer or parking official she had no right to see the badge, and refused.
She was still ranting and raving at me as the wheelchair hoist set the chair down next to me on the drivers’ side - she actually stepped back to make room for it. She suddenly realised what was happening as I got out of the car into the chair and followed me into the supermarket apologising profusely for her ‘mistake’.
So OP, I’ll tell you what I told her. It’s no one elses’ business if you are parking in a disabled spot and displaying a valid blue badge. No one other than a police officer or parking official has the right to handle the badge and access personal details from it. And no one has the right to demand details of what disability you have to qualify you (yes, at one point she did ask and got angrier when I refused to say). I always say that those details are between myself, my doctors and the badge issuing authority. I do try to be polite if I’m challenged - even when they’re still challenging after you place the badge (and some really do persist) but on a couple of occasions I’ve lost patience and as I wheel away, point them to the registration number, telling them to report me to whoever they like !!
I’ve found that since the pandemic this has actually got worse. Most people who challenge will say sorry when you produce the badge, but there seem to be a lot more people around who have anger issues and actively look for an argument. I really can’t be arsed with this attitude so if none of the above works, a simple ‘fuck off and mind your own business’ is usually very effective.
