Great doctor with an awesome bedside manner!

He is the worst Doctor that I have ever encountered. I was shocked by his rudeness and his refusal to even go over my test results with me. I am actually checking into this. There must be some legalities involved when I Doctor, who has already been paid, refuses to explain your test results.
