W: OK. This will be my treat.
M: Oh, no, you don’t.
W: All right, then, we’ll go Dutch.
M: Next time. This time you’re my guest.
W: Gee, it’s crowded.
M: Look, one empty small table by that big picture window over there. Let’s go and get it.
W: Ah, this is a pretty spot. You can see the people passing by while you eat.
M: And they can see you eat while they pass and that’s a pretty picture, too.
W: Is this the only type place for lunch?
M: There are some lunch counters, but they serve only a few specialties.
W: Why can’t you eat lunch in a restaurant?
M: Well, you can, but the service isn’t as fast. Most people only have half an hour to one hour for lunch. The time is too short for them to eat in a restaurant or to run back and forth from home to school or office, because the cities are too big.
W: So they eat quickly at the lunch counters?
M: Right. Lunch is normally a light meal anyway. Workers must either take lunch with them or get it near the place where they work.
W: What about the children?
M: Kids in school take sandwiches, fruit and cookies along with them or eat in school cafeterias.
W: This is delicious. If all the food tastes as good as this, I don’t miss our own food too much. I like American food!
M: I’m glad you enjoy it. Are you done?
W: I’m full.
M: Are you sure. You can get seconds.
W: I’m positively full. I have no more room. Wow, this will last me for a week. Thank you very much.
M: Don’t mention it.
