"After waiting so long to see the doctor, I felt he was very rushed in answering my questions. I understand the Doctor was trying to make up for an extended amount of time he spent with a patient that was before me, but I did have several questions that I did not think he spent enough time answering. Dr. Ahn is a good doctor and I will continue to be his patient, but I hope I will not feel as rushed when I am asking for his advice on eye problems I am having in the future."
