When I was a construction manager for a residential homebuilder, I used to drive by a Temp Agency on my way to work to pick up day laborers for doing stuff like digging, picking up trash, etc.
Although the laborers had enough motivation to get their asses up and be ready to be picked up at 6:30AM, a good portion of them really didn't feel like working when they actually got to the job site. I had picked this one scrawny black guy up for about a week straight because he was actually doing ok from day to day, but after that, he started to really get lazy on me. Then he started coming to work shitfaced. I told him he better tighten up or he was going home for good, and I would never select him from the group of available laborers again. He said it wouldn't happen again, and that he had "kids to feed".
Well, the next day I picked him up and as soon as he got in the car, he stunk like Mad Dog 20/20. I said to myself, "Well, this will be his last day but I'm not going to say anything until the end of the day because I need his ass to dig out a footer first. "

At around lunch time, I drive back to the job site to check his progress only to find that he's sitting on a drywall bucket with a crack pipe in his hand.
I lost it.
I said, "That's it. Your ass is going home.... now!"
Then he stared me right in the eyes and said, "Mutha fucka, you send me home and I'll hunt you down and pull an O.J. Simpson on your ass."
That was the first time in my life that I had ever been threatened like that. I grabbed the pipe out of his hand and through that thing as far as I could. He started crying like a baby!
I called a buddy of mine who was there on the job site as well, and we literally grabbed the laborer and threw him in the bed of the truck. I jumped in and took him back to where I got him and never saw him again after that.
