When Tarra slips upstairs and unlatches the attic window of the diner, there is no ruddy glow from the outside neon lights, as there is later when she and Matt enter through the same window after the inn closes for the night.
Matt's mom states that she and her husband had played the "Blue Eyes Crying In The Rain" record on the jukebox many times during the night while they'd been waiting for the torrential rain to stop so that they could safely drive home again. Yet the record sounds pristine and almost brand-new when Matt and Tarra dance to it. Any phonograph record --- especially a 45rpm disc that turns faster than a regular LP --- would likely sound at least a little worn after having been played that many times.
