I was parked (legally) and about to pull out when a van came and parked right next to me (illegally), blocking me in. When I politely asked the driver to move, she refused on the grounds that she was Belgian and I wasn't, so she had more right to be there than me(!) She then got extremely aggressive and started swearing and shouting at me.
It was really horrible, and I felt awfully impotent- I couldn't even just walk away as I had two children in the car. I just had to wait for her to go- I didn't want to escalate things as she was clearly just a horrible nut- while she shouted abuse at me from her van. How distressing ?
