I've actually thought about the "girls" comment before. I was trying to find a good word to call them. "Ladies" was what I used most and I got away from that when my wife worked up front. She said it made her feel old. I can't win. And my "staff" are younger than me so when I was 25 they were 10 and were "girls". Oh crap, it doesn't matter. I practice in freakin' Arkansas, do you think these people care? 99% probably don't even notice it.
Politically correct: Hell, I had a patient trying to tell me his primary care doctor's name but he couldn't remember it (Good as gold 84 year old). So he called the office (which has 5 different FP docs) and asked, "What is that black doctor's name?" Cracked me up. Did it in front of my waiting room. We all got a kick out of it and I told "the black doctor" the story and he said it didn't surprise him coming from that patient and laughed about it.
So I guess "girls" doesn't really phase most of my patients and definitely not my staff.
Point taken though.
