JE24 What's Your Problem

            During the summer, I went to Page One (a bookstore in 101) with my friends. I was going to buy the same book with one of them. We walked in and saw a discount section. Every book in that section only sells for about 99 NT dollars. My friend luckily found the book that we were going to buy. But I could not find another copy in it. I asked the people who worked there if I can get the same book at the same price in the discount section. But they said I could not. I asked for an explanation but they only said some unreasonable reason and tried to keep me off. Finally, I picked the book up reluctantly from the other shelf without any discount. It was unfair that my friend bought the book in about one-third of the original price. And it was pretty weird that only one copy of the book was in the discount section. How come my friend was so lucky to get a cheap book while I had to get it in the original price? And the salesperson could not even give me a reasonable reason! If I walked in the front and checked the section out firstly, I would be the one who got the discounted book.
