LOL @ Paul!
My father recently fired his doctor after the doctor asked him during an appointment "
You're not a diabetic... er, are you??".
I changed doctors after my doctor mis-diagnosed my pneumonia, and couldn't seem able to put three stitches in my leg without enlarging the wound, which then required 7 stitches at my local hospital...
There are some great doctors out there (like my new guy), but like everything, there's some real crud out there doing business, too.
