Is there a legal basis for the bookstore not to allow readers to copy books?

When readers enter the bookstore, they will naturally change into consumers, and establish a legal relationship between operators and consumers with the bookstore. As consumers, readers can of course browse books properly, decide whether to buy the book on the basis of understanding the general content of the book, and occasionally extract one or two pages, so long as the bookstore does not object, there is no problem.

But the bookstore is not a library, and this right cannot be abused. If readers read in the bookstore for a long time, or even extract a lot, it will undoubtedly harm the interests of the bookstore: first, it will affect the buying activities of other readers; Secondly, it is unfair for bookstores to reduce the chances of profit by selling books. Of course, in order to attract customers, many merchants now set up a space for readers to rest and read in bookstores and provide comfortable services, but this is not necessary, nor does it mean that readers have the right to read and copy in bookstores for a long time, but some merchants have given up their prohibited rights for promotion.
