Shame, shame Emily. Your Father-In-Law Is Dr. Krasinski, NOT Mr. Krasinski. I have patients actually come in my office, and yes while being examined and treated by me, call me Mr. instead of Dr. I myself, prefer my patients call me by my first name, but your Husband's father should be shown a little bit more respect by calling him in public as Dr. Sure, Dad, or whatever, in privately, but the title he has worked for, should be acknowledged publicly.
