Oh and here's an idea.
Tell her it hurt your feelings and ask her please not to do it again, even if it was a joke. Some things are just sore spots with people, and ask if she would have appreciated (even jokingly) you berating her for one of her hobbies in the middle of public.
Then, to show you're not being snide, invite her to become a bassist with you and show her the ropes. Or show her a great bassist on Youtube, etc. Who knows, maybe she'd dig that.
