So I know I probably was being unreasonable (pregnant, hormonal, toddler playing up royally that day!) but I just wondered how long I needed to feel mortified for.
Waiting to pull into a parent and child space but due to layout of car park other car got there first. Lady got out, locked car, started walking away. I couldn't see any child or car seat in the car from my view, so pressumed she was doing my massive bug bear of using P&C space with no child. So I wound down my window to call her out on it.
Coffe "Excuse me, how many children do you have with you to park in that space?!"
Lady "What?"
Coffee "It's a parent and child parking space for people with children!"
Lady"Of course I've got a child with me"
Coffe (hands shooting up to mouth in dismay) "have you? Oh I'm so sorry."
Lady (extremely cross) "don't you judge me, how dare you"
Coffee "I am sorry, you must hate it when people park in these spaces without kids too tho? I didn't realise"
Lady-storms off sending me evils.
I wasn't judging her and unsure how she thought I was, just when she locked the car and went to walk off without getting a child out, it looks like you dont have a kid with you surely! She was going to get a trolley which was obviously fine, and I won't be questioning anyone about their accompanying child status again, but it was a fair enough assumption no?? And I wasn't agressive about it at all!
Had to do my shop in Sainsbury's instead of Aldi as that's where she headed, and I was too miserable/embarrassed to bump into her.
Small local area and now living in fear of bumping into her 
How unreasonable was I?!
