Just read this post how horrible! I used to be manageress in a small shop years ago and would never allow any staff to feel scared, I didn't have to do anything as the owners would have been on to it like a ton of bricks. I now run my own business and would never allow any staff to feel threatened by some idiot. So glad it got sorted and she has support of yourself and boyfriend, it would have been so scary for her and she wouldn't have wanted a fuss when you know her manager. The guy probably doesn't have a care in world and better for shops reputation he is not aloud back in.
Well done you for not letting your daughter let it go and letting her know she wasn't making a fuss
