The customer observed how I did a jobsite receptacle and connected one black and one white to all devices--switches included. It took me more time to un-do and re-do than it would have taken to do the finish. Another customer paid for the rough and then said they would do the finish. I mailed them a letter telling them that my insurance does not cover work done by others and told them to torque the recep screws to the proper pound-inches as recommended by the manufacturer- and check for cross hot-back feed connections on each breaker.
