Oh, this is NICE! It's one of those things that makes your lips dry when you read it. I like your style as well as your vocabulary. You make the wording simple because that's your character, but I can tell that you have training or at least experience because of the very good flow of words.
If there was anything to say, it's very slight: The dialogue seems almost mechanical especially compared to the fluidity of the narration. That's all.
