ROFL! And that'll do it, too.
Thirty or forty years ago my wife and I were eating in a very expensive restaurant in Manhattan. There was a couple in there with a or 7 year-old boy. They let the kid run wild and scream NO! at them when they asked him to sid down.
The maître d asked them twice to control the boy to no avail. After about 20 minutes a man in a suit I assume was the owner came to the table with the boy by the hand. He asked the couple, Is this yours? And pointed to the boy.
The couple nodded. The man then said take him and leave. Your meal is complementary and you owe nothing for the evening. However, do not return. Youre no longer welcome here.
The couple took the kid and left.
I thought it was the way every restaurant should handle disruptive kids.
