Once in a soap industry in Japan,da soap cover was mistakenely packed widout soap in it i-e empty box.2 avoid da problem in future they purchased X-Ray machine of million dollars 2 check whether soap is filled in cover or not in assembly line.
Same problem arose in a poor city of Pakistan. Wat did they do?They simply put a rotating fan beside assembly line.Empty boxes were flown away! Genius!
