[speaker001:] Excuse me, Ma 'am. I would like to mail this package door to door via airmail to London. It is a very important package and has to be sent within 3 days.
[speaker002:] No problem. But, the postage is much higher than the regular package.
[speaker001:] That's fine with me. I am willing to pay for it as long as you can guarantee me the package can arrive in time.
[speaker002:] OK. All the registered airmail packages can be received in 5 working days.
[speaker001:] I see. How much do I need to pay in total for this package?
[speaker002:] It's 500 dollars.
[speaker001:] Can I have the receipt? Just in case I can trace it if something goes wrong.
[speaker002:] Sure! Please just fill in your I. D. number and ways to contact you here.
[speaker001:] Do I need to include my zip code in the address?
[speaker002:] You had better include that because it is easier for the mailmen to find the correct mailing address.
[speaker001:] Thank you very much. Here is 500 dollars.
[speaker002:] Here is your receipt. Contact us if your friend still doesn't receive the package after 5 work days.
