The world is full of funny and wtf moments. Jobs are done by humans and humans most definitely aren't perfect. You can't always expect people to get things done the right way the first time, especially if they never received any company training. These folks more than likely wound up in a company manual of what not to do.

Check out these funny examples of people who had one job and failed miserably. Mistakes were made and people were fired... hopefully. If they were fired, hopefully, they realized the error of their ways and took the necessary steps to correct their behavior or skillset before moving on to the next job because if not, they probably won't last long there either.
