I am older now, and blessed with great PPO insurance. If I don't like someone, I don't have to see them, and I have dropped doctors in the past because they were bullies or didn't really seem to give a shit. The gynecologist who left me bleeding heavily because he ratcheted the speculum too hard and chewed me out for not having had a Pap smear in two years at the age of 22? He did not get a repeat visit.
And yeah, I know my situation is not typical for a US resident, but I am grateful that I have these choices. Some of them are my own; I pay for the privilege, but I'm glad to have the option to do so.
In her defense, she seemed like she was new. The last nurse there was very polite. This one was young and, I suspect, idealistic.
My doctor's great, though, and that's really all I care about!
