Where are each of the two speakers from possibly?

M: Hi, Christi, I brought you some tea.
W: Thanks, Mark. Too bad it’ s not apple tea, like in Turkey.
M: Yeah, too bad! You really liked living in Turkey, didn’t you?
W: Yeah, it was great. Turkish people are so warm and generous.
M: How do you like the food in Turkey, Christi?
W: Oh, the food was fantastic ! But you know what I couldn’t get used to? How much people expected me to eat, I gained so much weight while I was living there!
M: Yes, it’ s so polite to be generous. We think people aren’ t polite if they don’ t offer a lot of food.
W: I know. I also learned that it’ s not polite for the guest to accept the offer of food at first.
M: Yes, that’ s definitely tree! If you’ re the guest, you must refuse the first two offers of food.
W: The first time I had dinner at a Turkish home, I felt rode refusing food. So I ate everything. And I kept on eating. . , and eating. Every time the host offered me something, I ate it.
M: Do you know how to stop the host from offering you food? You must leave some food on your plate. That way the host knows that yon’ re full.
W: Oh, is that the trick? In the United States, we usually eat everything. You don’ t want the host to think that you don’ t like the food.
M: That is a difference. You know what happened to me the first time I had dinner at an American home? When my hostess offered me a second helping of food, I said" no" the first time, to be polite. But she didn’t offer again! I was still hungry when I left the house!
W: Americans think it’ s not polite to insist. We don’ t want to force you to eat more if you don’ t want more. So if you say" no" the first time, we believe what you say and we don’ t offer again.
M: I learned that lesson the hard way. Now if someone asks me if I want something, I say "yes" the frost time -- even though I feel rude.
W: Would you like something to eat?
M: No, no, I am not hungry.
W: Ha, ha.
