Imbalanced
My coworker had to substitute for me to do some technical services at a petrochemical plant. He instructed the customer to pump some chemical into the system to boost the pH.
He however never told them to stop and they ended up pumping the entire 14,000 gallon container of chemicals into the unit which stopped production for 2 days, and they had to dump the solution in the process, which costs like $75000 or so to make.
Customer was furious and refused to pay for his visit. I am glad they didn’t sue us. Meanwhile he continues to sit in his office and ruin everything he touches. Story credit: Reddit / ooo-ooo-oooyea
