Place it at the start of a countdown sequence, then follow the ignored deadline with the Fail Sound Meme when nothing happens. For a refusal scene, cut to Darth Vader No Sound next, and use It Was At This Moment He Knew before the consequence lands.

This just-under-four-second clip captures ED-209, RoboCop's heavily armed enforcement droid, giving a suspect twenty seconds to obey in a flat, processed robot voice. The calm, emotionless delivery makes the deadline feel tense and absurdly serious, then darkly funny because a polite countdown masks a lethal threat. It comes from the 1987 film RoboCop, during the droid's boardroom demonstration.
