A: I need to exchange this DVD player, please. B: That won't be a problem if you have your receipt. A: Here you go. B: Now, if you'll just tell me the problem, please. A: It won't play my DVDs. B: This is a good product. I wonder what went wrong. A: I don't know. I trust this brand. This was a fluke, I think. B: You're right, this is a good brand. This new one should work just fine.
