I get that. I wasn't trying to insinuate that it would be an impossible to enforce. I was merely pointing out that 16 year old teens are old enough to work there, but not old enough to be there after the clock strikes _______? 16 year old kids can be employed (even younger, but most states have strict labor laws for anyone 15 and under) by this age, thus, have money to spend. It is also the legal age for driving, thus IMO, is an age where they shouldn't have to be attached to their parent's hip after 6 PM. I don't know the law in every state in this nation, but in PA (my home state), these 16 year old teens are legally able to drive alone (if they hold a jr. license of course) till 11 PM.
I certainly support the mall's right to impose such restrictions. They are after all, privately owned. I just don't think it's one of the better, most rational decisions that I've ever heard (though I think it's a great idea for the 15 and under crowd). That of course is opinion only and obviously the owners of this particular mall disagree.
As for anyone commenting on how delinquent these kids are acting, well, that's an entirely different subject, and mall security should be on top of it.
