Why is the woman calling?

W: Hi, Mr.Olson? I’m Eun-hee Sohn from Circle Optical Supplies. I’m calling about the order you placed yesterday.
M: Oh, yes—I ordered supplies for my eyeglass store. Is there an issue?
W: Well, we only have 25 of the eyeglass cases you ordered. Unfortunately, we won’t have any more in stock for another two weeks.
M: Oh, no—we have a promotional event starting next Friday, and we usually provide a case with each pair of eyeglasses our customers purchase. Hmm... I guess I’ll take the 25 cases you have, but I’ll have to order the rest from another company.
W: OK—I’ll update your order. And as an apology, my manager told me to waive your delivery charge. So, we’ll cover the twenty dollar shipping fee.
