A boss that I had, he want that I made 40 cables, at the beginning for me was like, my boss is stupid, he hates me. When I finished my work he told me that the cables were too short in this precise moment I decide to change my work. If your boss tell u that u can buy the cable, please do it and don't ask for the other way because in the moment that u make a good cable u are expert in making cables.

I think that this question you can ask to Hollywood. I'm complety sure that this question has been made before by this people.
