M: Good morning, madam. Is anybody taking care of you?

W: No, not yet. Could you show me that overcoat, the silver gray one in the middle.

M: Certainly. You've got excellent taste. It's very nice and it's 100 percent wool.

W: I like it. Could I try it on?

M: Certainly. It looks good on you, madam.
