"Positive feedback"

I went for my smear test recently and the lady that saw me was lovely! As loads of us know this test is not so comfortable and people might even put it off because of this. The nurse was nice, friendly, clearly knew what she was doing and made me feel better about being such a baby during the test. I’m not sure if we normally receive a feedback form after an appointment but it would be nice to be able to let her know that I appreciated her work this day.
