When Rob says he likes to dress nice, he's fiddling with his ascot, but when the scene cuts to another camera, his hands are in his lap.
Jerry Helper says he will start Rob's training at six bells. When Rob asks when that is, Jerry says it is about 6 o'clock because at 12:30 you add a bell every half hour. While the latter part is true, that means six bells is 3am, not 6am as Jerry stated.
