Not really on the toilet
In the scene where the gunman comes looking for Redford in the public bathroom only to find "Salino"'s legs showing through the bottom of the stall ignores a practical reality which would have given away the situation in real-life: there are no panties or other underthingies dropped around her ankles - which is a sign that she was faking it. A real gunman intent on finding Redford would have realized the fake and busted into the stall.
"Don't call me 'honey', mac."
"Don't call me 'mac'... HONEY!"
