When will they meet? Where does the woman suggest that the man get change?

M: Look, Lynn, I think I have to make our meeting on 18th of October to another day. You see, I have to go out to our branch office in Los Angles to attend the opening ceremony.
W: Em, yes, let me have a look. Mm... How about 21st?
M: 21st... Oh, I have an appointment with my lawyer on that day. Is 22nd OK?
W: No problem. I’ll write it down.

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.
