At the post office, the facilities that process bulk mail and 3rd class parcels are full of huge machinery, and to be sorted, packages travel along series of conveyor belts and are fed onto large slides which funnel them to sorting stations. Invariably, things will break open due to the weight of all the packages above them, or insufficient glue or tape on the box.
Once a box of big floppy books made of brown paper( like grocery store bag paper) broke open, and I had to gather them up, pack them back into the box and then re-tape the lid. Turns out these were magazines in braille, and on the cover of each was printed in black letters the magazine name and the date, issue & volume numbers. What blew my mind was that some of the magazines were Playboys, and one of the cliches of the day was that some guys really did read Playboy for the articles. I decided that was true, but mostly, the guys who read it for the articles were blind.
