Just had an run in with a woman who parked in the space next to me whilst I was paying for parking. She was not straight in the space, so she could open her drivers door but I couldn't open my rear door to get my sleeping toddler out. I called her out on her terrible parking and moved my car to another space.
She followed me and started shouting at me "do you want to look? I'm in the lines" I think she wanted a medal?! to which I replied "Yes but only just and it's more the fact that your car isn't straight but not to worry I've moved my car" she just kept saying "take a look, I'm in the lines!" She was right in my face and only backed off when my child woke up. Although she carried on shouting things at me when we crossed in the street later "child spaces!" I'm thinking she's never had to find one in a busy car park 
AIBU to think she is crap at parking and that she should have been grateful I said anything and was prepared to move my car rather than waiting for her to walk off and then ramming my door into the side of her car which my partner may well have done?
