How did the man learn of this place?

M: How much do you charge for a piano lesson here? I was recommended by a friend of mine who took lessons here a couple of years back.
W: Well, we charge by the hour here, and it’s 20 dollars an hour.
M: Wow, that’s a bit too pricey. Is there any type of discount considering the fact that I am going to sign up for a year or so.
W: Well, we do at times consider giving a discount, but you’d have to pay the entire fee in advance. Why don’t you sit down, and I’ll tell you more about it.
