That was rude of her. To play devils advocate, she did ask you to shave his face for the visit, so maybe she thought you were being rude to her by not doing that?
I keep my kids face shaved as often as I can. I do it just about every 2 weeks because it starts to drive me nuts when it gets much longer than that. So maybe she figured that you couldn't spare 2-3 weeks of your poodle having a shaved face? I don't know.
I've found most breeders to be absolutely insane, even the good ones. So I wouldn't put too much thought into it! You don't have to be advertising her dogs for her, that wasn't what you signed up for.
