My dear oversaw a project for a large mining company (normal for Western Australia) & required him to be on site for x amount of time. When you hear what every second word is out of the mouths of not only the normal engineers but also the high up dudes, it's no surprise that you'd have to be a tough nut. He dished it out as it fast as it came.

I'm tough but not tough enough to deal with mine sites...

I've had managers swear when the proverbial hits the fan..oh well..
