What would you think?
Imagine you are Embry. You ask McKittrick a "yes or no" question. McKittrick know that Embry needs an immediate answer and that serious consequences will follow if he and Embry misunderstand each other.
In that circumstance, he gives the affirmative response, "‘Go ahead, you're all right. Get your men out, and don't let that worry you.”
Would you interpret this as a promise of continued employment?
