"Rude staff and double standards"

I attended Sale Emergency Department with my sibling and their young child who has been having breathing issues, coughing, minimal fluid and solid intake and temperatures (suspected croup as I believe it had gone through the daycare centre). After they have already been up there for 2 hours earlier in the day and made to wait outside in the cold with also their other infant child as they had no car with them, they were told it could be a long wait and try to get a drs appointment. My sibling managed to get into the drs in the afternoon for a phone/Telehealth appointment when listening to my sibling's child they said they immediately needed to go back to emergency.

We headed back to emergency, a full waiting room and again told they would need to wait outside as my sibling's child has respiratory issues. I asked to speak to someone higher up in regards to this. A senior nurse I believe, came out who again said my sibling's child needs to go outside as they have respiratory issues. I asked where a policy was stating this, they advised they don’t have one or anything in writing stating this. I advised as there is no policy in order I will not be taking my sibling's young child out into the cold air whilst they are having breathing issues. They then rolled their eyes at me and looked at my sibling and said do you want your child on the list or not. My sibling responded by saying of course I do I’m here for care for my child to get a response of, then you need to wait outside. Again I advised until I see a policy regarding this we would not be as the only sign about respiratory issues states cough, cold, fever, runny nose and asked why a child needs to be outside yet a person sitting in the waiting area who I believe was blowing their nose constantly yet isn’t being made to wait outside in the cold like my sibling's young child. The nurse then responded to tell me they would find something in writing and I also asked for a complaint form. They walked off again rolling their eyes I believe. We stood for a couple of minutes until another staff member asked us to wait in between the 2 sliding doors until they came back. I did this while my sibling went to sit in the car. After 15min another staff member came from outside asking if I needed help with anything. I advised I was awaiting a complaint form and something in writing regards to my sibling's child being forced to wait in the car, they responded that they were the coordinator and asked to come speak with me. After 20 minutes of communication relating the same thing as in side, asking why there was, in my opinion, double standards in regards to respiratory issues. It was then made that an isolation room would be organised for my sibling's child to sit in as to not wait outside.

The coordinator Tracy whom I spoke with was very apologetic and listened to our conversation, where compared to our experience with the first nurse being made out to be an issue and I felt, too much trouble for them.
