A: What is this? I didn't order it.
B: I'm terribly sorry. What did you order?
A: I've ordered pasta.
B: Sorry, I must have made a mistake. I'll bring it to you at once.
A: And what is this?
B: Sorry. But didn't you order the mushroom soup?
A: Oh, is this the so-called soup?
B: I think so. But if it really bothers you, I'll change it for you.
A: No, no need to do that. Give me a refund.
B: Sorry. I'm afraid we can't. But you may order something else.
A: Oh, really? Then give me the chicken soup.
B: Okay.
A: You'd better hurry.
B: Sure. I hope you enjoy your dinner.
