Madonna: Dunkin' Donuts

The Queen of Pop was not cut out for customer service. Before making it as the Material Girl she was fired shortly after starting her job at Dunkin’ Donuts for squirting jelly at a customer.

In an interview with Howard Stern, he asked her “Were you fired because you squirted jelly over everyone?”

To which she replied: "I was playing with the jelly squirter machine, yeah.”
