Depends on many variables.
If it's my boss, then I have to be cautious. He fears me but he can still cause me career troubles.
If it's an intern he needs to learn to shut up and listen pretty bloody quickly. I can wreck his future.
If it's a complete stranger and the LOOK doesn't work, they get an earful.
If it's a religious nut on the street or at my door they need to learn what "fuck off"means, quickly.
