The service loop is where some really stupid mistakes happen. Comical stuff. Last summer we were doing a cabling job with about 150 drops and each cable was labeled at the service loop with a number (at the very end of the cable). We left for a 30 minute lunch. Another tech showed up from my company and cut off all the numbers.

Worse - pulled a 12-strand MM fiber that was preterminated on both ends. Before I could say 'stop' the tech working with me cut off the ends, all beautifully terminated. I hung those off my rear view mirror in my van for a long time.

Yet another time, a contractor came in and cut off all my cabling above the ceiling tile because it looked messy and they wanted to impress the new owners.
