"No care or compassion shown"

My mother-in-law recently attended A&E via ambulance. She has alzheimer's and was agitated and can become aggressive. We were advised she would be seen in triage and not have to sit in the very busy waiting area due to her agitation. However,  she was seen in triage and then advised she would have to sit back in the waiting area.

The manner in which this was communicated to us by the A&E staff nurse was inappropriate and had a very angry and aggressive tone.

We can absolultely appreciate the volume of patients that were in the department was unprecedented and that the staff are working in very stressful conditions and in a system that is over stretched. I believe the information that the nurse provided was factually correct  but there are ways and means of communicating.  

There was no care or compassion shown in this encounter but rather it  left us with an impression that my mother-in-law was a burden.
