let's get this straight

1. Let me make sure I have a clear understanding of the topic of discussion. A: "Let's get this straight—you expect me to do whatever you say, no questions asked?" B: "Yes, that's right. That's how you'll earn that big paycheck I've offered you."

2. Let's clear up any possible confusion, misunderstanding, or uncertainty (about something); let me make this perfectly clear. Before we get into this debate, let's get this straight—we are to focus solely on the topic at hand, so no deviating into unrelated subjects. Let's get this straight. I am the boss, and you are the employee, which means that when I ask you to do one thing, you're expected to do it.
