It is a really hit and miss when you come into a walk in clinic with different doctors since the most important aspect is who you would get as your attending doctor. For me, I had a female brunette doctor, and she googled my symptoms and went to wikipedia and read to me what was written on wikipedia. Sort of felt like the long wait to see her was a waste of my time, and so was part of my tax money. When I asked her a more specific question regarding my symptom, she snapped back and said she's not a specialist.
