Bart, I don't think you over reacted, if he walks like a duck he must be a quack.
Ten years ago my wife had open heart surgery. One of the heart valves was bad and it was replaced with a mechanical one. She wasn't healing quite right so back to the hospital where it was determined that she had a staff infection and she got it from the doctor. It seems that practically everyone he touched developed staff. She spent six weeks in an isolation room and would have probably died had not the head of infectious diseases stepped in. Her case was the straw that broke the camel's back as the head dude ran the operating surgeon out of town. I had let it be known that if he showed up while I was visiting that I had every intention of throwing the SOB out the window and her room was nine floors up.
On a side note, my wife goes in Tuesday morning for breast surgery and I pray to God that she doesn't develop staff again.
