When I go out to eat or some relaxation I do not think in terms of PC, OBP(other people's bullshit) or social grace and tolerance in these situations.
I think that I hardly ever go out and when I do it is to take a break from my normal routine. I think about the cash I am laying out and the goal is to relax...
What I do is ask for another seat somewhere else. I am not looking to create a more difficult situation if the child has a disability. If the kid is being a brat that is another story.
If it is a child behaving badly because the parents aren't parenting well, that's one thing. If it is a child with a disabiity, it's an entirely different matter. Possibly the mother didn't take the child to MacDonald's or the like becaus the atmosphere there would be far more difficult for a child with autism to handle. That could be very likely. Possibly she doesn't leave her with a baby sitter because it is difficult to find a sitter who knows how to take care of a child with autism. Possibly she's a single parent who can't afford a sitter and wanted a nice meal out for a change. Lots of possibilities here that make this not a clear cut case of just an annoying child with a parent making bad choices. How often does this happen to you, going to a 'nice' restaurant and dealing, not with poorly behaved children, but with a child with autism who may not be able to behave properly? Is this woman never allowed to go out to a nice meal?
Note in the article the restaurant manager says he lost a child. He is referring to his own gratitude of having a child at all after having lost his first child, and his gratitude she was okay, not burdened with any disability. Children are a precious gift, and those who are blessed to have healthy, ordinary kids are most blessed of all.
