What is rankism? First, some examples; then, a definition.

An executive pulls into valet parking, late to a business lunch, and finds no one to take his car. He spots a teenager running towards him and yells, "Where the hell were you? I haven't got all day."

He tosses the keys on the pavement. Bending to pick them up, the boy says, "Sorry, sir. About how long do you expect to be?"

The executive hollers over his shoulder, "You'll know when you see me, won't you?" The valet winces, but holds his tongue.

Postscript: That evening the teenager bullies his kid brother.
