I work as a Hostess at an Applebee's restaurant. It's as horrible as it sounds. I was eating some half-price food (which we get when we work a shift) and one of my friends, who is a server, pulled out what looked like a mushroom or a rock or something horrible out of the mashed potatoes. Aparently some of the not so edible potatoes get in to the bin of squashing and get mashed up with the rest of them. Thank goodness that it wasn't a customer that got it...
