A Boston Market employee is now without a job after showing his true colors to an executive.

During the Feb. 1 episode of CBS’s “Undercover Boss,” Sara Bittorf, chief brand officer of the restaurant chain, posed as a waitress to get a feel for goings-on at the ground level.

The reality show usually features higher-ups interacting with loyal and hardworking employees who are then handsomely rewarded for their dedication to their company; but the Boston Market employee in question, identified only as Ronnie, is the first worker to ever be fired on the show, according to Business Insider.

Under the guise of Rachel Rand, a waitress appearing on a reality show to win a chance to open her own restaurant, Bittorf began working at a Boston Market location in Duluth, Ga., and was trained by shift supervisor Ronnie, who spent most of the time complaining about customers.

“I literally hate customers more than anything in the entire world. I hate them so much,” he told Bittorf, fully aware that his words were being filmed on camera.

“They're terrible. It's all about them all the time and they demand everything.”

Shaken by what she was hearing, Bittorf had to excuse herself and went to the parking lot to think.

“My job's on the line. Here I am a representative of this brand and this is what happens. It can't happen on my watch,” she said as she contemplated her next move.

“I can't have someone who just told me that they hate customers more than anything in the world serving our guests. That's the complete antithesis of what we stand for.”

Bittorf then decided she needed to break cover and lectured Ronnie on his behavior. Then she revealed her identity to the branch manager and advised that the wayward employee be fired. Ronnie was sent home that day.

“I would tell them my attitude would change, but I didn't think it was that terrible. It's not wrong of me to hate people,” he said on camera after Bittorf revealed herself.

“They don't know I'm saying it, so it's not that big a deal, but now this giant lady of Boston Market knows what's going on, that's just not fair.”

Bittorf spoke with Business Insider shortly before the show’s airing, explaining that she had no choice but to fire Ronnie because he “wasn't living up to our values.”
