Granny and baby parking.

How unbelievably thoughtless and selfish.

Let's hope that when she does actually need a Mother & baby spot they're all full of equally selfish old women

Some people just don't care about others. I have a blue badge and sometimes can't get parked in a disabled bay and I've been told just to park in a parent and child space because that is 'allowed' - wouldn't do that even if it meant I couldn't do my shopping as it could mean that a genuine person with children who needed that bay wasn't able to get parked.
It's the culture of not giving a d...n for anybody else.

IMHO that's wrong. Similar to parking in a disabled bay when the badge holder is not in the vehicle

That is really awful. I don't blame you for not arguing but that really makes me cross. I see parents doing it too and once told someone that they appeared to have lost their child. They had no idea what I was saying and I wasn't brave enough to point it out in simple terms.
