Registration person flipped out over my daughter's...

Registration person flipped out over my daughter's service dog and refused to have anything to do with her. The n she said she couldn't find her orders which the women's center attached to the hospital easily found. Was she denying my daughter service because she was disabled? Or was she just so stressed she couldn't perform her job? Either way, that person needs to be reassigned. My daughter is embarrassed and devastated. This person should not be working at a hospital. This is not just a one off thing. It's been this way for many years. I only go there because of my insurance.
Update 10/19/20 I did talk with Alan. He listened very well and said he had already been aware of the issue from another employee I had spoken with. For confidentiality reasons, he can't discuss what has been done to resolve this issue and I understand that. However, after looking at the most recent reviews and the difficulty I had with post nursing at my daughter's surgery on 9/23/20, there appears to do a very systemic issue with employee training in following doctor orders, learning how to access orders, behaviors and attitudes towards disabled people/service dogs and discussing disabled people within other patient's hearing. Those are serious violations that would result in dings during an audit from medicare and the state.
