Don't stick your foot there!

It's a story we've seen all too often - something gets stuck in the cog of a machine and standard protocol is to power everything off, get a worker in there while he's being monitored, and make sure he's able to carefully extract whatever's causing the problem. Time and time again, innocent workers go into machines without realizing that the person responsible for turning everything off actually forgot.

United Airlines just showed us all the worst customer service imaginable

None of really enjoy airports. They're busy, stressful, and even when you get through security and find yourself at the right gate, your reward is several hours sitting on a stuffy, crowded airplane. Most of us just want to get through our flight as painlessly as possible so we can get on with our lives. For one group of passengers on a United Airlines flight, things took several hours longer and got much, much worse than anyone anticipated.
