I parked in a disabled bay today when visiting a friend. I am disabled but not particularly visibly, and displayed my blue badge. The bay was outside a row of houses but on a public road, not allocated or private parking. There was no where else to park on the street.
As I left a man came out and started yelling at me about how I shouldn't have parked there. I was polite and told him I had a blue badge and was entitled to park there. He continued to yell at me, asked me how I'd like it if he parked on my drive (not the same thing at all) and told me "park there again and see what happens", so I told him I'd be sure to let the police know. He then told me to fuck off.
So, was I being unreasonable? I have checked and it's much like parking on the pavement outside someone's house - they don't own it and as long as you have a blue badge you're allowed to park there. I don't think I did anything wrong, but he was incandescent with rage.
