An Iowa man recently had an experience in a restaurant that left him scratching his head. He says that the server added 20% automatic gratuity because they were a party of six.
His issue isn’t with automatic gratuity itself. He’s miffed because the sixth person is their 11-month-old infant. And three of the diners are their small children.
