ABC News catches up with Adam Smith, the Tucson CFO who destroyed his career after harassing a Chick-fil-A drive-thru worker over the company's financial support of organizations that oppose gay rights. From the report:

Things haven't gone too well for the former CFO who criticized Chick-fil-A in a video he posted on YouTu A former CFO is now on food stamps after a video he posted on YouTube two and half years ago criticizing Chick-Fil-A went viral and destroyed his career.

Adam Smith, 37, was the CFO of a medical device manufacturer in Arizona, until the summer 2012, when he — and thousands of other people — started protesting against Chick-Fil-A for the fast-food chain's anti-gay stance.

One day, Smith decided to go through the drive-thru at his local Chick-Fil-A, where he ordered a free water — the fast food chain offers customers free water — and videotaped himself telling the drive-thru attendant how much he despised Chick-Fil-A.

"Chick-Fil-A is a hateful corporation," Smith said, in part, to the drive-thru attendant. "I don't know how you live with yourself and work here. I don't understand it. This is a horrible corporation with horrible values. You deserve better."

Smith then posted the video on his personal YouTube channel, but when he got back to work, he received a major shock.

"I got into work and the receptionist, the first thing, big eyes, 'Adam, what did you do?' ... she said, 'The voicemail is completely full, and it's full of bomb threats,'" Smith said in an exclusive interview with ABC News' "20/20."
