"Unacceptable staff attitude"

My parent has just had cataract surgery and went to the Sydney Eye Hospital Emergency Department to get their eye dressing removed. The nurse who attended to us was, in my opinion, very rude. They would, in my opinion, scream at my parent if they didn’t do what the nurse asked or when they misunderstood. They were very unpleasant to deal with. The nurse would tell us, this is how you do it and I would just nod my head. And then they screamed at me, do you understand?, two times like as if I didn’t understand English. And later my other parent wanted to confirm if we’re supposed to use like a fabric tissue or just normal ones, and they asked the nurse again who screamed back, I told you before - Tissue! I think it’s so rude to treat someone like that! I hope this story gets read.
