re: the 30 minutes you sit in the examining room before they walk in
And the 45 minutes or more sitting in the waiting room before being ushered into an examining room.
Whenever a doctor has kept me waiting for more than 15 minutes from the exact time of my appointment, I bill him for my time and deduct it from his fee. When I explain that my time is just as valuable as his, I never get an arguement. All the doctors I use now are trained and have their staff usher me in as soon as I arrive even if others are in the waiting room. If you act like a sheep, expect to be herded!
