Who most likely are they?

W: I’m terribly sorry, Henry, but I am going to have to cancel the meeting tonight meeting. I just received a call from Mr. King, a very important client of mine, and he says that he is in the area and he wants to come over to the office at 6 to talk to me about something. Do you think we can get together another time?
M: Sure, we can always catch a flick this weekend.(54)Who is this Mr. King guy anyway?
W: Oh, he is the owner of a fabric manufacturing firm that I recently sold a group policy to.(53)He mentioned something about wanting to increase the size of his group policy.(55)
M: Wow, that’s great. I wish more of my customers would come and visit me to buy extra coverage.
