I am often amazed at the complexity of forms in general and wonder how others manage to complete them as i often struggle.
I am also disillusioned by the use of the blue badge system overall, a colleague whose partner is eligible for blue badge used to abuse the system regularly once with a bunch of us in the back, no non-ambulant people involved he parked up threw the badge in the dash and strode off! He seemed un phased by our protests, he seemed to think it was his bonus for all the times when he had to help is partner when she was with him!
Equally I had an elderly friend who genuinely was in a bad way, he didn't bother to apply for a badge, even though he would probably have been eligible, he would occasionally use 'parking spaces close to the door' including dedicated blue badge spaces, and to me, common sense suggests that this was reasonable. Its just that common sense just isn't very common.
We have these rules because some people struggle with the concept of being reasonable.
