Dick.

In retail, it is generally one's job to greet customers at or near the front door.

One of my employees (we'll call him "Carl") was assigned to do just that. Then this happened...

Carl: "How are you doing today, sir?"

Dick: "I don't answer that question!" stated very pretentiously. Dick then turns around and leaves.

If Carl would have then said, "Go fuck yourself, sir!" I wouldn't have fired him. I would promote him.

Don't be a Dick.
