N.G.
I would definitely let the doctor know about it. In my experience, when I tell a doctor that his staff sucks, he/she takes action.
My ex family physician (now retired) had hired a new staff and they were a bunch of unprofessional brats. I alerted him to the fact (apparently I wasn't the only one complaining about them) and within days, they were all fired.
That's extreme, but this Dr. needs to know because he/she could be losing business because of these rude ladies!
