Once in a soap industry in Japan,
the soap cover was mistakenly packed without soap in it i.e an empty cover.
To avoid the problem in future they purchased X-Ray machine of 60 thousand dollars
to check in the assembly line that
whether soap is packed in the cover or not in.
Same problem occurred in Pakistan.
What did they do??
They simply put a pedestal fan beside the assembly line.
Empty boxes were flown away! :-D
