Definately a good idea. Tell her that you have no idea who the guy was, you showed up as promised and this rude guy ordered you to leave. You made arrangements with her so you need to hear it from her. If you had a written contract follow up in writing. My opinion on this whole situation is that if you run a business, in this case daycare which involves something as sensitive as kids, it's not a good idea for word to get around the community that you employ somebody like that.
