The shot in which Diane goes to the soda gun to fill a glass of water is shown twice. The camera angle is different the second time it's shown.
(at around 12 mins) A line of Diane's dialogue is dubbed over a shot in which her lips don't move.
As the next scene begins just after the "fine dribble crystal" gag, during the long shot of the bar pointing towards the pool room, studio can lights can be seen above the bar and going down the hallway.
