We’ve told you before of Walmart employees who were fired for intervening in violent or potentially dangerous situations at the store, but here’s a story of a Walmart worker who’s in trouble for not stepping in. Of course, it doesn’t help that he posted video of the incident along with his wisecracking running commentary.

CBS Dallas has the tale of the Arlington, TX, Walmart employee who posted a video on Facebook of what appears to be a customer attempting to steal items during the self-checkout process. As he films the shopper, the employee mocks her efforts at thievery.

He then follows along as she tries to leave the store.

“Have fun,” he taunts, as someone grabs the bag containing the allegedly stolen items. “Have a good day.”

The cashier-cum-cameraman also got footage of the wannabe shoplifter getting into a scuffle with another woman in the parking lot.

Other employees stepped in to try to break up the fight while the cashier continued capturing it all on video.

That’s when he says something that probably sealed his fate at the retailer.

“Yup, and I let it happen,” he says to his own camera, “on the Walmart clock.”

Rather than just show the footage to pals privately, the employee posted it on his own Facebook page.

Not surprisingly, this didn’t go over well with Walmart HQ.

“This type of behavior by a Walmart associate is completely unacceptable,” the company tells CBS. “We are conducting an internal investigation into this matter at this time and will take action as appropriate.”

The employee who shot the video has apparently “resigned” from his gig at the store. No word on whether or not any other workers will be penalized.
