What does Alison order? Which machine are the people talking about?

A: So, Alison. Do you know what you want?
B: I’m not sure. The chicken sounds nice, but so does the fish. What about you?
A: Well, I think I’m going to have the fish.
B: OK. I’ll have that, too.

A: Karen, Could you help me for a moment?
B: Sure. What’s the problem?
A: I’m not sure how to use this machine.
B: It’s very simple. Just insert the paper, key in the number and press the send button.
