The dialogue describing an everyday purchase situation was presented for role playing, and oral practice, being the underlined segments examples of:

Salesman: Madam, how may I help you?
Customer: I’m looking for a leather purse.
Salesman: What size do you prefer?
Customer: Medium.
Salesman: What about the brand?
Customer: Maybe an Italian one in red.
Salesman: It won’t be a problem. The section on the left has new famous Italian arrivals but I’m not sure we have all of them in red.
Customer: The variety there seems far less. Anyway I will see the second, fourth and sixth red Italian ones on the first row to start with.
