I was standing in line in a book store waiting for my purchase. The cashier had one of those ear pieces for walkie talkies.
Suddenly she touches her mike and says, "I'm helping a line at registers, can someone else get that?"
It takes her all of five seconds.
Her current customer throws a fit, calling her rude for talking into her walkie while a customer was right in front of her. She won't be appeased, no matter how much logic is applied, or explanations given.
Finally the cashier turned to the Information Desk, several yards away, cups her hands over her mouth and bellows;
Cashier: "HEY [NAME]! A CUSTOMER SAYS IT'S RUDE OF US TO USE OUR WALKIES TO COMMUNICATE! SHALL I SEND A NOTE TO CORPORATE?"
And without missing a beat, the coworkers bellows back,
The cashier gives her customer the biggest, sweetest smile and says;
The customer muttered something inaudible and scurried out like a cockroach when the lights come on.
I told that cashier that she was my hero.
