Lets face, there are places and places.

I was talking the other day to a friend who had the "misfortune"of having to dress as Santa in a five-star hotel for an event aimed at kids. The poor guy had a massive hangover that day and he was telling me how over a hundred crazy kids run towards him and he managed to scape thru the service door with some kids hanging out of his belt. Of course you would expect kids to go a little crazy and over exited at the time. And so you would expect them to run around crazily in a christmas lunch aimed at kids and families.

I'm not saying let your kids rund wildly at all times everywhere. If those kids were REALLY vandalising the place and posing a danger to themselves and others then parents, hotel staff or other adults would have intervened.

Lets get real, guys, if you go to a hotel for a family aimed event then you will have to expect to encounter noisy kids running all over. I don't see what's the big deal with that.
If you want a relaxed meal choose any other day of the year.
