In the final scene, when Amanda says, "You mean when I had my hand up your pants? Men are so easy", Tom's line is "Oh, yeah". But he is kissing Amanda at that moment, so his lips are otherwise occupied.
When Tom goes to the Southern Cross to break up with Amanda, he ends up helping instead, waiting tables. The plates are plain white with gold trim. However, these are not any of the three plate patterns Amanda picked out in the department store that Tom paid for.
When Amanda goes to Tom's office to return his wallet, Tom's shirt sleeves are rolled up to the top of his arms. When Jonathan enters the room, Tom's sleeves are at his elbows. After Amanda leaves the room and they shoot back to Tom and Jonathan, Tom's sleeves are all the way back up again.
