I don't know anything about this particular child's health or history but there are thousands of people, including children, who suffer from various bowel disorders such as Crohn's disease, colitis, proctitis, IBS...and having access to a restroom is imperative.
Of course, crapping all over an inhospitable business owner's floor isn't such a terrible thing...from my perspective but it's probably not too pleasant for the one with tummy troubles. LOL
I also noticed that in the article linked in post #27 it said there were "at least a dozen" public bathrooms available in the vicinity. That sounds like an exaggeration so it seems like we have competing exaggerations here to me. But there must have been others if not fully 12 of them.
I also thought it was interesting that the store owner has been receiving death threats and harassing calls over this. The entitlement mentality in this world is going way over the top IMO.
