W: I need to find a baby sitter to take care of my son. Do you know Mrs. Peterson? I heard she is usually available at weekdays.
M: Well, I know that baby sitter. But the best I can say for her is she has a great fantasy to the TV in her living room.
Q: What does the man imply about Mrs. Peterson?
W: May I try this dress? Hmm, size 10, please.
M: Sure! Ma'am, we only have two of them left. They're on sale today, and the deal will be made on a first-come, first-served basis.
Q: What does the man mean?
