Things that I've learned at my many doctor visits recently..
The bigger the practice and the bigger the waiting room and the more recepionists, nurses, and other staff they have means the longer the wait time and the less personal your visit will be. Also, the more information regarding your symptoms they have you write down the more times they'll ask you what those symptoms are and why you're there. The more embarrassing the symptoms? Then the louder they'll ask and in front of more people. Seriously I'm not sure why they have you fill out your medical history at all- it's not like a single person looks at it. My new response when they ask me a question I've already answered on paper? "I believe that I answered that question on #5 on page 35 of your survey, approximately 56 minutes ago while I was waiting."
