听力原文：W: I just read a curious fact. Did you know that people who spend less than ten m

inutes in a drugstore are five times more likely to make a purchase than those who spend-half an hour there？

M: I saw that article, too. But think, if someone runs into a drugstore for ten minutes, it's usually to make a specific purchase.

W: And someone who spends more time they may be just looking.

M: Exactly. Haven't you ever gone into a store thinking that you'd like to buy something, and then talk yourself out of it？

W: Yes, I have, especially when I thought I would get it for less elsewhere, or I really didn't need it after all.

M: Exactly. But if you run into buying something specific and have very little time. You pick it up, pay for it immediately and then leave.

W: That's true. Maybe we should learn a lesson from that. Take your time and you'll spend less money.

M: I doubt if that would be true in all stores, though. In a department store, for instance, you may see a sweater or something you never intended to buy, and buy it be cause you have time to look around.
