M: Let’s go and get something to eat.
W: Oh, I’m starving. Hey, there’s a McDonald’s up there.
M: There’s always a McDonald’s-up-ahead. Everywhere you turn there’s another blasted McDonald’s.
W: What’s wrong with that? Hey, they’re convenient.
M: They’re too convenient![12]Anything would be convenient if it could be found on every street corner.
W: I like McDonald’s!
M: I’m sick of it. Did you know that there are over 8,000 restaurants in the US alone and over 11,000 franchises worldwide? By the year 2020, everyone will eat at McDonald’s everyday!
W: They’re definitely everywhere. But they must be doing something right: they’ve sold over 100 billion burgers. They’re even in Japan.[13]Did you know they even put special Japanese sauces on some of their burgers in Japan? That makes McDonald’s quite popular there.
M: Whatever, I just don’t think their food is all that great.
W: But at least their product is consistent; you know exactly what you’re going to get every time you go there.
M: Did you know that McDonald’s is now recognised by 96% of all American schoolchildren? They are the largest minimum-wage employer in America.
W:[14]I heard that a person working at a McDonald’s in Moscow makes more than the average Russian doctor does.
M: That’s disgusting! McDonald’s may earn a lot of money every year. They say that one in every seven American millionaires got their start at McDonald’s.
W: Oh, I’m hungry. Let’s hurry and find a fast food place.
M: OK. What do you feel like eating?
W: I’ve got this intense craving for a Big Mac.
M: I just lost my appetite. Let’s go somewhere else for a change.
