While Maisie and the soldier are talking in the diner, the glass of coke she's drinking changes positions and goes from full to empty at the end of the scene. Likewise, the amount of lemonade in her glass goes up and down from shot to shot when she's on a date with Flip at the casino.
When Maisie escapes a passed-out Clave, she goes across the hall to her room, but does not fully close the door. Tommy then knocks on her door, and when she goes to open it, the door is closed all the way.
