Tough call. Not everybody feels comfortable leaving their kids in the hands of strangers whenever they want a night out or go have a meal, but yeah, kids can be annoying to some people. They never bother me, but some of the parents do. My parents and grandparents would take me and my brother to nightclubs when they went dancing; there were always other kids there for us to run around with, and where we got our taste for live music and dancing ourselves. Got to see a lot of great musicians live, too, back when they got famous playing for audiences first.
It's also why we developed our aversion to excessive booze consumption, seeing what it did to some people's personalities. Watching alleged 'adults' fighting was kind of funny though, but nothing we hadn't seen at Little League and school sports games, lol. The umpires at ours were chosen for their size and lacek of inhibitions in fighting angry parents.
