In my case, if we go to kid friendly restaurants, we expect kids to be kids but when we go to "adult" restaurants we have the expectation of kids not being kids if they are there.
Just like there are certain restaurants that seem to think they also a concert arena with their "background" music levels, we avoid them like the plague.
Not all of us are sanguine in character so while your way may work fine for you for the rest of us there are certain restaurants that should (and some do) only cater to adults.
That is true, but sometimes if you consider a different than your usual approach - it might work better, than the usual one.
When I was a kid, if we were acting up my mom or dad would take up out of the setting until we behaved. Some parent's these days don't care and won't correct the child and we're not talking about kids playing with silverware.
well, a poster above complained that the kid next table was playing with silverware and it was annoying her - at the New Years Eve dinner ( sic!!!) aren't you supposed to be light -hearted and happy at such an occasion? If at the New years Eve dinner all you see is somebody's kid playing with silverware ( not even bothering YOU) - than it is not the kid who needs help, IMHO.
And generally I agree that parents nowadays are more permissive with their kids and while it might be annoying - it is up to you to allow yourself to be annoyed or not,
Just a suggestion, as you won't be able to change the kids and the parents.
