"AMU nurse with disgusting attitude"

I just visited my dad in AMU (acute medical unit) for the first time this evening at 19.20. Not knowing my dad’s whereabouts yet, I approached a nurse writing her notes at the AMU reception desk. She had her back/side to me and I cheerily said “hello”, as you do, and her response, or non-response as the case may be, was to remain facing away from me and ‘say’ “mmmmmm- hmmmmm” as if she were a waitress in an American diner and I was a worthless customer there to order some fries. She offered me no respect or recognition that I was a concerned person here to visit a loved one. I said to her “you could at least say hello instead of just making a noise at me”. She looked at me with a smirk and attitude all over her face, as if to say, “I really could not care for you”. She then proceeded to point me in the incorrect direction and walked away. She could have not been more rude or unhelpful. I told the other 2 members of staff who witnessed this that her behaviour was disgusting and someone should have a word with her. If that is the way she speaks to visitors, I hate to think how she speaks and ‘cares’ for her vulnerable patients. Members of staff like her a contributing factor to why the NHS gets a bad name. Disgraceful!
