Barbet Schroeder's Reversal of Fortune ('90) delivers one of my all-time favorite endings, which isn't an "ending" as much ironic commentary about the mindset of a rich, very blase sociopath (Jeremy Irons' Claus von Bulow) and the difference between the "little people" and the Fifth Avenue elites who occasionally pop into this or that store. The scene happens between :50 and 1:25. HE comment: The checkout clerk had it coming because she was so unsubtle when she stared at the front page of the New York Post. She did it so blatantly that she forced Von Bulow to respond.
