"W" and "M" in the conversations stand for "woman" and "man".
Teacher: Now, understand the problem? Solve this instance: W: Can I help you, sir? M: Could I change my order? I just want the sandwich and not the soup. W: I've just handed in your order, sir. I'm not sure if I can change it now. I'll ask the cook.
