So Screwed

We had lunch yesterday at one of my favorite restaurants. We don't go there often because it's an hour away. I didn't know it was the type of place to serve a fancy Sunday brunch, but we were hungry and all the other food is good there, so we dove in and ate the buffet. I was enjoying the mashed potatoes-one of my most favorite foods-when I bit into something hard. Of course, I spit it out, right onto to my plate (because I'm classy like that) when it made a loud clank! I had bitten into a screw. It wasn't a long screw, it was one of the short fat ones, but a screw nonetheless. I kept feeling my teeth to make sure I didn't chip one..I didn't. Good thing it was mashed potatoes so I wasn't chewing too vigorously. The manager came over and apologized for it. I wasn't a crab-ass or anything, I understand things happen. If I had been feeding my child and that happened, I'd be irate. Or if I did chip a tooth. Our meal was comped and I left hungry. I was grossed out and couldn't eat anymore. Apparently, the screw came off the mixer that they used for the potatoes. I would think they'd notice a piece of the mixer was gone, but I guess not. Now I wonder, how dirty was that screw I almost ate???
