I actually did not have to call. The dentist office called almost immediately after and left a message to please call. Like I said, there were 2 older assistants in the office and they were just as mortified.
#1. Evidently new gal did not do her job, she was supposed to tell me the teeth may be impacted and that the dentist would be out in a few minutes to explain. She never got that far, only far enough to make the rude comment.
2) Other, older assitants must have ripped her a new one. When I called back and said who I was every one immediately began apologizing and put me on hold to talk with Jill the office manager. Jill, the office manager said that I can expect a formal letter of apology and wanted to know if I wanted to speak with the Dr. I said no, that I had full faith that she (Jill) had things well in hand with her staff.
3) evidently the young lady has a chip on her shoulder because she went to one of those "technical" schools that you see advertised on tv. She claims that she was told her certificate would enable her to do more and make more money. When she got the job she found out that what she actually wanted to be was a dental Hygenist which from what I gathered is more training.

I'm not in the field so I gather there is a difference.
Thanks for all the clever, snappy come backs. I'll be seeing new girl again if she last that long.
I do want to say, that I am glad that I didn't cause a big argument in the office, so maybe my shock was a good thing. I would not wish unemployment on anyone but as another poster pointed out if I own a business I would want to know if my staff was running around insulting people.
