He told her that he only wanted to "*beep*" her, but nothing was implied, unless I missed something. I don't think he liked her or found her appealing, however, he could have had sex with her just to make her suffer.
shareWe're only left with the impression that he raped her. Her facial expression when he makes the advance clearly reveals she wasn't interested, and that a date meant a date to her. She even talked on the way there about her her brothers being overly protective. I take this as her way of telling him that there wasn't going to be any sex. He commits another rape that we do see later in the movie. This brutal scene I think also gives us the disturbing answer as to how the situation with the fast food clerk ended.
shareI think he raped her, he was rather happy afterwards so I don't think she got away. And I don't think she'd fall for his unconventional seducing technique.
He knew he'd get away with it cause he was a cop.
A good father and a good outlaw can't settle inside the same man.
