Works for every situation. Combat, drywalling, house framing, bottle recycling, metal scrap collecting/stealing, sitting in the corner rocking back and forth...
I don't know I have a flooring company and it's just me and a couple employees I have and one of them was smoking meth and became the worst worker ever and I had to fire him. He would crash and sleep for days not showing up or answering his phone then he'd be all fucked up on meth rushing things and breaking stuff in customers homes ect. Just awful and unreliable, an absolute loser.
