Why is the woman pleased?

W: I’m really excited at how well we’ve been doing with sales this year. I’m signing a contract with a major department store later today. They’ve agreed to carry several lines of our clothing.
M: That is great news. But are you sure our factories are capable of handling all the additional production?
W: Actually, I’m going to suggest to Ms. Raines that we expand our domestic plant and recruit some additional workers. But I’m not sure if she will like the idea.
M: I’m sure she will understand that it’s necessary. Before you make the recommendation, you should contact the local factory manager and get a rough estimate about costs.
