听力原文：W: I've just read a curious fact. Did you know that people who spend less than 10 minutes in a drug store 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 drug store for 10 minutes, he is usually there to make a specific purchase.
W: And someone who spends more time there may be just looking？
M: Exactly. Haven't you ever gone into a store thinking that you'll buy something and then talk yourself out of it？
W: Yes, I have. Especially when I thought I could get it for less elsewhere, or I really didn't need it after all.
M: Exactly, but, if you run in to buy 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 end 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 some thing you never intend to buy, and buy it because you have time to look around.
