Was working as a mashgiach in a not so well known kitchen. I walked into the kitchen to begin my shift at 4pm. Supper preparations were well under way. The Rav Hamachshir happened to come in with me. He saw something on the grill and asked the mashgiach who was going off shift what was on the grill. He replied, they are grilling burgers for dinner. He was promptly fired. (They were kashering livers!)
For every “horror story”, there are thousands of vigilant mashgichim making sure you are not eating treif daily. Dont panic.
