Clerk: Hello, how can I help you?
Anne: I’d like to send this package, please.
Clerk: Would you like to send it by airmail or by surface mail?
Anne: By air. It’s faster that way.
Clerk: Yes, it is. Do you want to send it as registered mail?
Anne: No, that’s not necessary.
Clerk: Is there anything else?
Anne: Yes. I’m writing a letter to my parents back home. They live in Australia, and I write to them every week. Could I have a book of overseas stamps, please? I’ll send the letter later, when I finish writing.
Clerk: Here’s the book of stamps.
Anne: How much do I owe you for that?
Clerk: That will be £3.20 for the package, and £1.50 for the book of stamps. Your total is £4.70.
Anne: Here you go. Thank you for all your help.
Clerk: You’re very welcome.
