We have to be careful how we word things...

you're child has the following symptoms, she needs to be picked up right away. Are you able to come now?

If not... move on to your back ups. That's why we have them.

I used to work half hour away from daycare with no traffic and it was not a job that I could just leave on a moments notice, but if my daycare called, I dropped everything and I was out the door. And if not... I had a reliable back up.

I'm sorry your morning went so poorly. Make sure you speak with them about it when you see them again, or make a phone call. I would hate for htis to happen again.
