The Terminator1984

Terminator:
I'm a friend of Sarah Connor. I was told she was here. Could I see her please?

Desk Sergeant:
No, you can't see her. She's making a statement.

Terminator:
Where is she?

Desk Sergeant:
Look, it may take a while. Want to wait? There's a bench over there. [points to bench]

Terminator:
[looks around, examining the structural integrity of the room, then looks back at him] I'll be back.

[shortly afterwards, the Terminator drives a squad car into the precinct's reception room, crushing the desk sergeant against the back wall by ramming the car into the desk] Note:
