Michael Scott: No, no, you're not- You are not going anywhere. You're going to stay here until we figure this out.
Pizza guy: What?
Michael Scott: You know what? This young man needs to learn that that's not how you treat people. I don't care if it's pizza. Good business is about respect and accountability and follow-through. You don't just make promises and pull the rug out from under somebody, do you? Dwight, please escort this young man into the conference room. Right now. Get in the conference room.
Pizza guy: I'm not going in there.
Michael Scott: Yeah, you are. Yeah, you are. And you will come out when you decide to give me a discount on the pizza. Please. Thank you.
Pizza guy: This is stupid.
Michael Scott: No, you don't even know what stupid is! It's about to get all stupid up in here!
