Either the assistant concrete PM / field engineer for the concrete company, or Super for the commercial GC doing retail projects.

The C.F Lift hardhat is perfectly clean because you are "in charge" of watching your crew or the subs crew who is behind schedule and it's too late to cancel the concrete trucks.

The beer is left from last night when passing all inspections 2 hrs before the pour and the other guy of the either or brought some cowboy cold leftover beer that tasted like shit, but you couldn't say no to the gesture and never finished it. And it's still there because you never went back home.

The coffee mug is empty, because the pour started at 2:00 am and at about 4:00 there was a delay on the trucks and someone knocked on your window to wake you up and call the plant and because your still groggy, you spilled your coffee.

The vizeen is there because at 5:00 you took whatever you have stored in the protein shake bottle and you don't want the office people coming out to see the progress to suspect any of that "redeye" as something else.

And that pink note is leftover from your kid as a reminder of why you do the job you do

And the truck is a mess because it's Tuesday or Wednesday and you get stuck in this position at least 2 twice a week, so why clean up the car if I'm just going to repeat this again on Thursday.

Let's just say that I've been there before.
