How did the man learn of this place?

W: Hi, is there anything I can help you with today, sir?
M: Yes, I was told by a shopkeeper down the road that you specialize in clothes for big people.(44)I’ve been looking around this entire area for the last hour, but I have not had any luck yet. I really do hope you have what I am looking for.
W: Yes, I think we may be able to help you out. In fact, the entire second floor completely caters to people who are considered big.(45)If you walk up to the second floor,(46)you will see there are many fashionable clothes to choose from at very reasonable prices.
M: Wow, this is wonderful. I don’t understand why I’ve never heard of this place before.
