Other mistake: Although it was pouring rain, no rain came into her car when Deb opened the window. Similarly, the floor by the front door of the convenience store (gas station) stayed dry despite customers coming in during the ongoing heavy rainfall. (00:25:24)
Continuity mistake: Upon arrival at the gas station, Deb parked her car at a slant (diagonally) and somewhat distant to the front door, but when she was leaving, her car was perpendicular and closer to the front door. (00:21:37 - 00:24:43)
