[speaker001:] Hello, I bought a China dress in your shop this morning.
[speaker002:] Yes?
[speaker001:] I bought one size up by mistake.
[speaker002:] Oh, did you?
[speaker001:] I wonder if you can change it to one size down.
[speaker002:] Yes, of course. Will you come with receipt?
[speaker001:] Then I 'll come to your place later in the evening, and how late is your shop open?
[speaker002:] Until 8 o'clock madam. We are looking forward to seeing you.
