OMG I am disgusted. I got angry just reading that! I am trying to put myself in that situation and imagine what I would do but I can't think of anything...maybe I would have thrown the basket at her, but then I had a minute to think so I probably wouldn't have.
I would try and find out who she is and notify the police. I think that having the police turn up on her doorstep would be the ultimate response.
I hope you are all okay xx
