Goodwill Industries complaint: Cashier was extremely disrespectful

I wanted to address this situation because I have never had a bad experience in this store until today. I was shopping with my two daughters and at the cashier (Bridget) was being very disrespectful refusing to give up news paper to warp our glass items and said there was none and screaming at the other cashier that there was no paper, when it was visible. My daughter pointed it out and she threw it on the table. I have always taught my daughters to be respectful but to see someone be so disrespectful was hard to watch as a mom. We left and I thanked my daughters for not saying a word. I understand people have hard times but we did nothing at all to this woman for her to treat us the way she did. Please advise her to get help if needed, no one should go through this. I thank you in advance for your attention to this matter and for all the other cashiers that go beyond to make us all feel welcomed.
