[speaker001:] Hello, I bought a pen in your shop just before.
[speaker002:] Yes, thank you very much.
[speaker001:] Now I came back to the hotel and try to show it to my friend, the pen is broken, I am afraid.
[speaker002:] Oh, is it?
[speaker001:] Would you change it to a new one?
[speaker002:] Yes, certainly, you have the receipt?
[speaker001:] Yes, I do.
[speaker002:] Then would you kindly come to our shop with the receipt by 10 o'clock, we'll replace it.
[speaker001:] Thank you so much!
