Where may this conversation take place?

M: I’d like to mail this package to Hong Kong. How much will it be, please?
W: Do you want to send it first class or parcel post?
M: How much is the first class and how long does it take?
W: Your package is light. First class would cost $ 8.20. I guess it will take about eight to ten days to arrive.
M: And parcel post?
W: Sending it parcel post would be cheaper, but it wouldn’t arrive for about a month. The rate for parcel post is $ 4.90.
M: Oh, I want it to arrive earlier than that. I’ll mail it first class. Also, I’d like to insure it for $ 30.00.
W: What’s in the package? I need to know in order to complete the form.
M: A pair of glass earrings. I packed them well, so I’m sure they won’t break, but I want to insure them just in ease. Are there any other forms I need to fill out because it’s going to a foreign country?
W: Yes, one more. It’s customs declaration on which you declare what item or items are in the package and their value.
M: Here it is.
W: Incidentally, you forgot put a return address on this package. It’s not a post office regulation, but we strongly recommend that all mail have a legible return address.
M: OK. I’ll do it right now. I’ll also buy ten 60 cent stamps.
W: Let’s see. The package, the insurance, and the stamps. Your total bill is $18.20.
M: Thank you. Have a nice day.
