No. First of all, if Jean is constantly late, you'd think the dentist in charge would speak with her. My guess is he thinks she's so good, people will wait and he'll keep their business. If she wasn't late, you'd be on time, that's not right. Especially when you have other responsibilities. Sorry, that's way to long to wait. I can understand an emergency, but not a constant thing.

Unless you have oral problems, I'd try another hygienist, just for the heck of it. If you're not satisfied, then you'll know the wait for Jean is worth it.

I just think it's plain RUDE.
