Similar situation happened to me when i took my gorgeous boy to a pet store few years back, and these 2 old ladies came to me same way it happened to you , they claimed to be show breeders of another breed and yorkies and asked me if my boy was pure because he actually looked way to big and they did not wanted to offend me to just say he was a mix. My boy is a gorgeous all standard looking 5 pounds, blue and gold, nice conformation even to his age, perfect ears and baby face. Of course i have nothing to do with the big hair, he proudly wears a very fashionable puppy cut , but he was pointed out as a "short haired yorkie" and we all know there is no such thing, he was trimmed to my very own choice of hair trim.
I dont usually share this episode, but if it will make you feel better you are not alone. To those 2 old ladies and the lady who met you i have only one thought, they must envy yorkie owners and were never able to get one for themselves.
Good day
