Enough negativity about jobs that sucked... how about jobs where you were able to drink (or partake of other substances...), whether or not it was permitted?
I go first...
I was about 19 and worked in a body shop sanding cars. The owner had one of those old Coke machines.. guess what? Those little Michelob bottles were a perfect for for it. He'd stock it up in the morning, no charge. He was a 5-star drunk and most of us drank our share.
One day, after work, I was riding with the boss to pick up my car at his apartment. I left it there in the morning as I took a customer's car into the shop. Well, he's pretty sloshed and manages to run his van into the back of a car that had stopped in front of us. We were driving right into the glare of the sun.
He gets out, looks at the damage, the other person calls the cops. My boss goes to his van, starts tossing empty beer cans into the woods. It seems that some guy walking his dog standing there watching rats him out. The cops test him and locks him up on the spot. I hoof it back to the shop to get a tow truck to get the van. He winds up with a DUI out of it.
About 3 weeks later the shop burns to the ground. Part of it was a repair shop and a car with a leaky fuel line sat in there all night. The first person in flips the lights on and BOOM!! Lucky nobody was hurt. Just as well for me.
