What does Alison order? Where does the woman suggest that the man get change?

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.

M: Miss, can you give me change for a dollar?
W: I’m sorry, sir. I’m not allowed to give change without a purchase. If you go across the hall, you’ll find a change machine in front of the bookstore.
