Oh goodness...I used to work at Hallmark. And the parents would let their kids run around breaking the merchandise. All they would ever do is say "Stop that," or "Leave that alone." But they would never shown any seriousness about it. Then, they got mad if the manager said "if they tear the tag off on more item, you are buying it" and would never come back. I always say when I have children of my own one day - they will NOT act like little monsters like they do today.
Sorry I get started very easily on kids and how they act today in public. My mother taught me at an early age to not act like they do today. I acted out in church once and after I got spanked - it never happened again lol.
