Where does Stephenie Meyer appear in the film Twilight?

In the scene where Bella and her father are in the Diner for the second time in the movie, Stephenie Meyer is sitting at the counter in the Diner. She is wearing a red shirt, and she is typing on a laptop that is on the counter. The waitress sets a plate down next to her and says, "Here's your veggie plate, Stephie." Not the first time they are eating in the Diner, but the second time, after the guy in the boat is killed.
