It's no longer part of the job because people are too dumb to use an extension cord and hang themselves.
If it's not obvious, my words are over the top, but it's not an exaggeration to state that dumb people have a massively outsized impact on how companies and mfgs approach retail offerings.
It's also no exaggeration to state that revenue is up by doing so. The stupid tend to self select out of the market when we don't try to make it easy and that has saved us man years in customer service topics for people that only survive due warning labels.
