We've all got our fair share of "never again" moments. Some might be related to debauchery, for example, swearing off tequila after an unfortunate binge-drinking episode back in college. Some may involve moments of staggering stupidity. Other "never agains" might be a little more serious, like refusing to work in a restaurant or in retail. This r/AskReddit thread covers all of those bases and more, with plenty of "facepalm" moments to keep things light.
