Last spring in Boise, a guy watched me put a service loop in his crawl space and said, 'That extra cable looks lazy, cut it flush.' I told him sharp bends kill the signal over time, he shrugged and said, 'My last guy did it and my internet was fine for 4 years.' I left the loop, he called to complain, and the next tech got chewed out too. Anyone else have a client fight you on basic physics and win?
Why do customers always think their one good experience means the rules don't apply? I had a guy in Nampa who insisted I staple the coax tight to the stud every six inches because the droop "looked trashy." Told him staples pinch the cable and crush the shield, he said his old setup ran fine for years. Six months later his speeds were tanking and guess who got the callback? Not the old guy, that's for sure. You did the right thing leaving that loop, it's there for a reason and it ain't decoration. Some folks just gotta learn the hard way and then blame you for it.
