【正确答案】Candidate A: You know, I'm crazy about VTP, that is to say, virtual team purchases. Every day I spend a lot of time on those coupon sites, hoping to find the way which can save money for me. Candidate B: Well, what coupons do you think can bring real discounts to us? Candidate A: I think coupons of food are sometimes real bargains, especially those of famous or chain restaurants. Using the coupons of food, you can enjoy the same food and service with a quite lower pay than usual. But you'd better not buy coupons from small restaurants, or you will be trapped. Candidate B: Well, last week I was trapped by a small restaurant, which has shown itself with amazing pictures online but actually very disappointing. This makes me determined to give up buying those food coupons. You know I also find some other interesting team purchases online. For example, I want to have a haircut, and then I find there are many such coupons for me to choose. Can you give me some suggestions? Candidate A: No problem. I think firstly you should make sure where the barbershop is and you should also pay attention to the products they will use on your hair. It is very important for your health. Candidate B: Thanks a lot. Have you ever bought some other coupons online? Candidate A: Of course. I've bought various coupons and I almost haven't enough time to use them. Maybe I should not be so impulsive.
