Who is Mr. Wells talking to?

W Good morning, Mr. Wells. This is Kimmy Delane from Discount Travel. I’m calling to see if you are still interested in the package tour for Thailand? Today is the last day to make a reservation.
M Oh, really? I’m still interested but I need to ask my friend if he still is. We had planned on traveling together. Let me call you back later. Is that all right?
W Sure, I’ll be here until 4:30. Call me back by then so we can finalize your reservation.
M All right, I’ll call before lunchtime if I can contact my friend.
