A: Hi, taxi!
B: Hi. Can I help you?
A: Take me to the post office,please.
B: OK. Which post office would you like to go to?
A: Any post office is OK as long as I can send a letter by airmail.
B: Is the general post office OK?
A: Yeah, but how long will it take to get there?
B: It's about 40 minutes' drive.
A: That takes too long. Is there a post office nearby?
B: Yes. But I don't know if you can send a letter by airmail.
A: So I'd better go to the general post office.
B: I'll try to drive fast.
A: Thank you very much.
B: It's my pleasure.
