I am currently at an outpatient appt at my local hospital. Getting fitted for a vaginal pessary 
This is taking a lot of re-fitting and I am basically being taken between patients to go up sizes until they get one that fits. While we were waiting for the nurse to get the next size, the Dr started dictating a GP letter about the person who was in before me. He got as far as patient name, address, date of birth and presenting symptoms when I pulled back the curtain and said "excuse me, do you realise I am here?" (I was right next to him but with a curtain between us). He looked very confused and said yes and went to continue. I said I felt very uncomfortable listening to someone's personal clinical history and that I would be very upset to think my problems would be discussed in a similar way in front of other patients. He apologised and stopped but explained it was routine practice to save time.
Was I unreasonable?
