Imagine "her horror" as the daughter "recoiled" at the assistant asking her politely if she needed assistance. 🙂
All this weaponizing of outrage. I see Rowling is now involved calling for a ban on M&S, an esteemed British shop over precious little.
If she was that worried about the assistant just ask for someone else. But then it wouldn't have created a stir, which was clearly the intent.
