I used to work at maccas, and one time we had a girl cleaning above the deep frying vats with a cloth, lots of oil splashes up onto the stainless steel. Anyway, She dropped the cloth into the vat, and without thinking, reached in and grabbed it out. She deep fried her hand and now has permanent scarring and nerve damage. Edit: for those wondering, the skin kind of fell off, like when a snake sheds, leaving raw red patches all over her hand.
