Once, post-tornado, an untrained groundie, without permission, decided to move the truck up a bit to let a neighbor out of their driveway, while I was craning out a tree, and the boss was looking at trees on houses all over town. He didn't park the manual transmission in gear, only the parking brake, no chocks.
The mostly fully loaded chip truck, around C60, with a BC 1000 or better on it, started to ever so slowly creep and start to pick up a tiny bit of speed. One of the groundies ran around and pushed the regular foot break, reaching in from the ground. It was about to go down a steeeep hill and possibly through an occupied house.
F*&^ing employees thinking that they should be making decisions like that...
