Where is Mrs. Smith most probably?

M: Please hold the line, Mrs. Smith. The doctor will talk to you in a minute.
W: I’m afraid I may have to hang up. I don’t have any more coins and the line will be cut soon.

M: You can get a lot of practice in issuing tickets and handling hotel reservations. Later on, you can take telephone calls.
W: That’s great! Thanks, Mr. Thomson. I’ll come to work tomorrow.
