Oh Blu, you've made me sad. I thought they did it because they loved me and wanted the best for me.
I did it yesterday too - guy on his own, 50s, driving the wrong way round the car park too. So I waited until he reversed up so that I could pull into a place, then he pulled into the next one.
I opened his door (I really can't believe that bit) and calmly explained that these were for people with children and why it was important and that he'd gone the wrong way anyway. And I finished by saying "so I'd like you to repark now please"
What a teacher!!!
He did, though!
