There's nothing worse than someone getting your McDonald's order wrong.
It's happened to all of us - you asked for a Big Mac and you get a Quarter Pounder with cheese. Not cool.
Though it's always a gut-wrenching moment, you usually just make do with what you have, or just complain about the employees to your friends if worse comes to worst. What you don't do, however, is storm the McDonald's branch in question and open fire at the terrified employees.
Amazingly, this is what one unhappy customer did when she discovered that her fries were too cold for her liking. Upon her luke-warm discovery, the woman returned to the branch in Georgia, all while wielding and firing a gun.
It's a miracle that no one was hurt...
