The technicians in Electrical industry are always taught to provide a service loop while wiring. This is done to accomodate future wiring or re-routing which may require a little bit more length of wire.
This photograph shows a distribution pole of Pakistan Telecommunication (PTCL) in Karachi. It is amazing to see how much length of wire has been provided as service loops here. Bravo to technicians who are actually able to track which wire goes to what subscriber.
It somehow also shows highest degree of unprofessionalism and untidiness. May be such a mess is part of self-constructed job-security for technicians as only those can navigate this maze without any schematics.
