You've never heard of the New York Yankees? ,F: I'm a huge baseball fan. I know who the Yankees are, but why are you wearing that hat backwards? What are you 10 years old?

Please hold on for a moment. ,F: Alright. ,M: Hello? ,F: Yes, I'm still here. ,M: Well, there doesn't seem to be any problems with your account. The billing is accurate. You must have overlooked the international call you made to Europe. ,F: Let me see. Right. I'm sorry, it's my mistake. But it is still very expensive. ,M: Well, why don't you apply for the international dial service? It's free of charge. ,F: Can I do that? ,M: Sure. You can.

Thanks for calling.
