I had a janitor job one time in a class 10 cleanroom.
Basically, its a big dustfree environment for manufacturing computer parts. The company billed out 10 hours a night to wiping down the walls and other tasks inside the cleanroom...night after night i wiped and no dust, no dust, no dust. So, I started riding the pallet jack all over the basement, raiding mini fridges in the office complex, renting movies to watch in the meeting rooms, and finally i started going home and going to sleep every night..
I worked(lounged) there for 2 years! I finally quit the job, but was shocked no one ever ratted me out. Alot of nights i was praying someone would- just to end the misery haha..Ive found its better to be worked to death than bored to death anyday
