I worked at a fast food place when I was young that served fried chicken. The fried chicken always took longer than everything else. One day I was left by myself for an afternoon shift without really knowing what to do. I'd never worked that shift and the person that was supposed to replace me never showed up. The chicken orders started showing up, I hadn't realized I was supposed to have started cooking chicken about a half hour before then. People were pissed. Most people ended up waiting at least 20 minutes. A few people just straight up left.
