Corrected entry: The perfect breakfast sandwich is constantly changing. When Sal passes the sandwich to Harley, it's a flat, toasted bread sandwich in plastic cling wrap. When she picks it up off the counter, it's wrapped in tin foil. When she eats it on the street, it's a sandwich with buns wrapped in yellow paper.
Corrected entry: After buying an egg sandwich, it focuses on the fact she is wearing one flat shoe and one heeled boot. She is then chased by the police and is wearing two flat shoes from then on.
Correction: When getting the sandwich, she has socks on, and a shoe on one foot. She must kick the shoe off off-screen, and is then just running in her socks.
Correction: The sandwich is actually wrapped in tinfoil, not plastic wrap, when Sal passes it to Harley, When she goes outside, you can see the tinfoil fall to the ground at 0:13:48, right before she attempts to take a bite.
