Apparently they served a 4 year old a mudslide instead of a chocolate milkshake at a Chili's in Chicago, and this kind of stuff has been happening recently. I can certainly see being upset, but I don't get the calling police thing over an honest mistake. Anyway, you can read about it, and some other incidents like it, here:

I guess the moral is that we should all at least smell the drinks our kids get at restaurants before letting them drink them.
