A: When are we going to stop? B: We'll stop at the next McDonald's. A: How far away is that? B: I think we'll be there in half an hour. A: I hope so. I have to go to the bathroom. B: Well, I can always pull over. A: No, thank you, I'll just wait. B: We can kill two birds with one stone. A: What do you mean? B: While you're using the bathroom, I'll order some food. A: Don't order for me. I'm not hungry. B: I'm very hungry. I'll order for you, and then I'll eat yours.
