Where does the man work?

M: Fabulous Florists, this is Andrew Sullivan. What can I do for you today?
W: Mr. Sullivan, I may have your mobile phone. I found it under a table at a restaurant and thought I should call the work number I found in its directory.
M: Thank you very much! Yes, l thought I had lost it somewhere on the subway this morning. I’m so grateful that you called me. It is such a relief!
W: I thought it was the right thing to do. l work at TC Bank on Roosevelt Street and I leave at about five, so please come to pick it up before then.
