input question: M: Is anything wrong, Madam? W: I'm afraid there is. The service here has been terrible. We had to wait twenty minutes for a glass of mineral water. M: I see. Well I'm sorry to hear that. The trouble is that we're a bit sort of hands at present. Two waitresses are ill. W: All right, but that's no excuse. My husband asked for goose and he was brought chicken instead. It's just unbelievable! And my beans weren't cooked properly. It wasn't a very enjoyable meal at all. M: This is most regrettable. W: Look at this bill. We've been overcharged. We only had one dessert, not two. Can you check the bill again, please? M: I do apologize, Madam. W: I'm afraid I'm not going to pay the service charge, or give a tip, as I don't feel satisfied with it. I'm quite disappointed as a matter of fact. M: I'll pass on your complaints to the manager right away. W: Thank you. What was said before this conversation????
output answer: W: Waiter! I'd like to speak to the manager please... immediately if possible.

input question: W: I'd like some plants that can keep the earth fresh. M: Especially in this cold season when you can't keep die window open, isn't it? W: Absolutely. And something that's easy to care for and not expensive. M: OK, Miss. Our shop won't disappoint you. Look at these plants. They've just come in and I bet you like one of them. This is a corn plant. The tall tree can grow more than six feet and it doesn't need any water or light. W: Quite striking, isn't it? What's that? M: A palm. It adds a tropical touch to your room. The leaves are perfect for cleaning your air. It has a long life and it's easy to care for. W: Oh, this lovely small plant has beautiful white flower. What do you call it? M: Peace lily. Even the flower isn't blooming, its dense leaves look great. W: Perfect. It's just what I want. M: Won't you have a look at Janet Craig and Mother-in-Law's Tongue? And they're just as good. M: No, thanks. The peace lily is OK. The more I see, the less certain I become, you know. What was said before this conversation????
