It's all about the principle of the matter groundzero. Barminco are renowned for their underground work; they have saved many mines from premature closure and are often brought in by owner operator companies to reattain production guidance figures and save ongoing sales contracts from being compromised. They're kind of a big deal in the industry, but as a contractor they still rely on their professional image in order to retain and regain work. I can see the funny side to the video but ultimately the company's image has been compromised because of this group of workers.
If you wanted your house painted, would you get the village idiot from down the road or someone a little more professional from the next suburb for a little bet extra outlay?
