Just popped to my local Waitrose to restock on the Belgian biscuits (half price!). As I drove in I spotted a nice convenient parking space outside the front of the store and pulled in, only vaguely aware of a vehicle approaching from my right. As I pulled in to park, the driver of the car, a 60 something blonde, started gesticulating and waving out of her window. I got out, saw that the car park was half empty so load of spaces for her. As I walked into the shop she shouted that I was a selfish bitch and worse!! In the store I saw her in the aisle and mentioned that I didn’t appreciate being sworn at by a total stranger. She repeated that I was a selfish bitch and threatened to punch me. At that point I realised I was on to a loser and went home. She’d left a note on my windscreen for good measure, again calling me a selfish bitch. I actually think she would have punched me if I hadn’t walked away. 2 questions - am I a selfish bitch? Genuinely didn’t see her and car park was half empty. Should I have reported her to the store manager or are threats of violence a factor of modern life that we all have to accept?
