But once you know the range of social settings where you can expect your kids to behave, you can opt out of certain situations. I have two kids, both are now college age. We rarely took them to restaurants. It was unpleasant for us, unpleasant for them, and expensive. In fact I live in a town that's known for being a place to raise kids, and most people don't take their kids to restaurants that are not overtly kid friendly.
At the same time, people being more tolerant of the normal range of behaviors exhibited by children, could also be a matter of parents doing their job.
Just note that "noisy kid" may mean "parents are not doing their job" or "kid with ADHD" or "autistic kid" or "kid having emotional difficulties while parents undergoing divorce", etc.
