@Typo-MAGAshiv just remembered a vignette about the shop next door that did contact work for Enterprise Rental cars. Instead of proper used oil storage in covered tank with secondary catchment, they had 55 gallon drums full lined against a brick wall in the open. One hot day, one of his mechanics' last acts on the job, was the classic pulling a car out after a brake job without pumping up the pedal first. He slammed into those barrels with his foot trying to press the brake pedal through the floorboard. Parked on both sides were 1-2 year new Enterprise cars with all the windows down including the one he was driving. About 200 gallons of extra black used oil (Enterprise specified change every 15,000mi and filter only every second time) geysered skyward, and came down over all the cars and their open windows and sunroof. I came back from lunch to find the seldom seen staff of the print shop whose back wall was hit, grouped in our driveway watching the chaos of the staff frantically wiping up oil with months worth of shop towels and anything else, the Boss cursing the guy rolling his tool chest to the curb, and an ExxonMobil Valdez scale spill of oil spreading.
