Dude, you are making yourself look real bad.
You work at a shop, and is a total noob.
Your the reason local shop get such a bad name. They let idiots work their that shouldn't.
In almost every career, you need to know what your doing to get the job, minus car audio. Any idiot can run wires, and install a cd player and such.
This would be like me being a pilot, when I have no idea how to fly a plane but I've been driving a car for 10 years.
