If this is true, it's ridiculous.  Have you or anyone you know ever asked someone if they were pregnant and shouldn't have?  Well, a four year old did this at a doughnut shop in CT.  They banned him and his mom because he was "rude."  See the whole story from Buzzfeed, here.  His mom apologized, of course... was mortified.  Apparently the store manager hasn't been around kids (or adults).  They say "the darn-dest things."
