What is the most unprofessional thing a medical person has ever said or done to you?

Inspired by a comment another Jelly made about something a nurse said to her ex, that was WAY out of line.

For a while there, a couple of months, I was getting blood drawn about once a week, keeping an eye on my electrolyte levels. I had standing orders from my doctor at our local hospital.
The third time I went in, the lab tech says, pretty sarcastically, “Do you even know why you’re coming in all the time??”
I stared at her in disbelief and said, “Yes. I do.”
Then I filed a complaint. That’s when I heard that I wasn’t the only one who complained about her.
