In fact, the job of bookstore clerk is not easy. Not what many young artists think. They can read books most of the day. When they meet customers who need help, they just help them find books. Not at all, at least not in the bookstore where I work now. From the beginning, the bookstore clearly stipulated that no reading and no sitting are allowed at work. So think about it, the bookstore has regular classes. If you stand for eleven hours a day, your legs will be sore even if you do nothing.
