Hidden barcode
Barcodes are these little stickers you see here that are on almost everything inside a store nowadays. It prevents you from stealing objects without paying but alerting the detectors at the entrance of the store. Usually, they are placed in obvious places, but this bookstore took things to new extremes we’ve never seen.
We guess they just had enough of people stealing their books so they decided that the best thing they could do was hide their barcodes inside the pages. The only problem is that this ruins a page of the book that the buyer can now not be able to read. Talk about getting ripped off.
