Doctor who doesn't smile

I am not sure whether it is my conditioning, but I don't instinctively trust doctors who smile too much or try to be friendly to their patients. I guess I am just old school and I am not comfortable with doctors who go out of the way to put their patients at ease. Give me the gruff old school doctor who scolds his/her patients for not following instructions and doesn't prescribe too many diagnostic test or medicines.

And... I am also uncomfortable with doctors who write too neatly :-p
