Aww that so sucks foryou I am soo sorry , I hope thats the bottom of youre day and it goes up from there,
Maybe the kid was really sick and they just didnt think, there were times when My son was sick that I really didnt care if someone was offended by us because I was worried , he was littler but there were times I certianly wasnt gonna leave himi alone in a car or room or whatever to clean up something.
I am sorry though I would be upset if that happend to me as well.
