In two shots we see the list of brands that Misha is crossing out, he crosses out "Burger" with two lines. Later, when he is crossing out other brands, "Burger" has only one line through it.
When Abby is stripping off her blouse when she and Misha are stuck in traffic, she takes off her seat belt and puts it back on after removing her blouse. Then the shoulder harness disappears and reappears in between shots.
