I got my first job in the oil patch without asking. My Uncle called me and asked if I wanted to work. Of course, that was as a roughneck!
I showed up in the cafe where doodlebuggers had their morning coffee.
Was driving a water truck that afternoon, and running the rig a couple of weeks later (shot hole).
Left that job and got onto a big rig when a friend said he was twisting off that day, they simply put me onto the rig floor where he had been.
Great jobs. That was 37 years ago. I recall being sentient, showing up, and being able to dodge pipe stands as the only real job qualifications.
