I was asking a question, politely, and the doctor snapped at me. I understand the doctors are very busy and she was with a sick patient but when a patient asks nicely if an x-ray was looked at, then there is no need to snap back rudely. Btw I was waiting for 4 hours so I believe it should be understood why I asked. I even apologized afterwards.
