[speaker001:] Good morning. What can I do for you?
[speaker002:] Good morning. I want to post this letter. Can you tell me what the postage is?
[speaker001:] I must weigh it. Do you want to send it by ordinary or registered mail?
[speaker002:] I want this letter registered. There is something valuable inside.
[speaker001:] In that case, you'd better have it registered.
[speaker002:] I think so. Would you mind telling me the postage now?
[speaker001:] Seven dollars and fifty cents in all.
[speaker002:] Here is ten dollars.
[speaker001:] OK. Here are your receipt and your change.
[speaker002:] Thank you. Goodbye.
[speaker001:] Bye.
