Another ex-restaurant worker here; Bennigan's, TGIFridays, Red Lobster.
Most of the stores that I worked in were clean and most people had standards. I had high standards and many followed. TGI Friday's was by far the most militant (good way) of knocking out food and keeping clean.
The best story I have comes not as much from ignorance as much as it does stupidity. At Red Lobster, there was this manager named Stu. He was not the brightest bulb and he was a weightlifter/bodybuilder. Big upper body, smaller lower. For this, I nicknamed him 'Stu-roid'.
One weekend night I was off, but I had a friend call me to tell me what had just gone down. The snow crab legs come in frozen and we'd thaw what we were expecting to sell during the day/night. Once thawed, they'd be put into a steamer as ordered. Well, apparently either someone didn't thaw the right amount or they underestimated the business that night, and they ran out. Stu-roid, in a panic, grabbed lots of frozen snow crab legs, put them onto a flat, dish rack and shoved them through the dishwasher (think conveyor belt). Soap and all. My understanding is that someone had to explain to him, and pretty much convince him that those crab legs could not be served because of the soap.
For this, I nicknamed him Stu-pid.
