Patient verified via Press Ganey

She was the must rude doctor I have ever had. When she did finally join the call she was sitting back in her chair away from the computer so it was hard to hear you. Her body language and tone of voice was unwelcoming. Very closed off. Annoyed and make me feel stupid for asking questions. She didn't introduce her self. She joined the call and just looked at me waiting for me to say something. So I said hi and so did she. Then the silence began again. We just looked at each other. I was very confused and waiting for her to start the conversation. And said said " do you have any questions " I was dumbfounded and confused and asked if she read my chart and she said yes. Then more silence and staring. It was a complete waste of my time and awful bedside manors
