Chrysler's social media strategist sent the wrong tweet from the wrong account

Scott Bartosiewicz was a social media strategist in charge of Chrysler's corporate account.
One day, while stuck in traffic on a highway near Detroit, Bartosiewicz decided to tweet what was on his mind: "I find it ironic that Detroit is known as the #motorcity and yet no one here knows how to (expletive) drive."
The problem was he was logged in to Chrysler's official Twitter account, not his personal account. Soon, he was fired and Chrysler didn't renew their contract with his firm.
Later, Bartosiewicz said in an interview, "I poured all my heart and soul into that. It's unfortunate it's all being overshadowed by 140 characters."
