I'm a bit eh, but mostly I don't agree. Some of my earliest and fondest memories are of going out with my grandparents and parents. My Grandparents in particular used to take me to this restaurant that had children's meals that had containers shaped like policeman-dogs and cat-burglars, and so every lunchtime my granddad would tell me stories using these lunches. If I knew that someone was trying to or had managed to deprive me or another child of those sorts of memories (my grandparents died before I was ten, some of these memories are literally all I remember of them) then I would be so far beyond pissed at those people.
But then again, even at age five or six (and my parents insist even younger than that) I was apparently a quiet and polite child who understood that a restaurant was for your indoor voice, and not running around in either. I think that the problem here is not the children, but parents who can't control or haven't taught their children properly, and I don't think it's fair to deny children the chance to understand what it means to be an adult, and to 'feel grown-up,' as my parents used to say, just because some idiot parents don't understand about proper child rearing.
SO in short, no, I don't agree, and I think that the only people who genuinely agree with this are actually the selfish ones in this equation.
