"Are you serious?"
A guy figures out a clever way to rig his car so it appears that nobody is driving, and then pulls up to a drive-through window after ordering his food. The employees don't react with screams but with befuddlement, amused fear and laughter. Most of them call to a coworker to share the experience, and to confirm they aren't crazy.
My favorite comment? It's hard to pick, but a woman who tells her coworker to "Instagram dat joint" is near the top.
