Once I did some basement wiring in a ceiling electrical box which was already pretty loaded with wires. A few years later when a real electrician came across this, he kept saying while cursing every 2 words: "I don't know who did this %#$@? job, but I'd sure like to give him a piece of my mind!!!", and I replied: "Yeah, me to!" Honestly, these guys work fast and good and you have piece of mind.
