A Walmart shopper sloshed the blue liquid around in her mouth before spitting it right back in the bottle.
In a video clip, Bameron Nicole Smith is seen walking towards the shelf.
Smith then opens a bottle of the blue liquid, takes a sip of Listerine and dumps the contents back into the container.
The video continues with Smith commenting, ‘Mmm, nice and minty and fresh’, before appearing to walk away from the oral hygiene aisle.
Smith posted the clip with the following caption:
You bitches with no oral hygiene could take a hint.
Reddit users complain that the act is a crime and call for Smith’s punishment.
A social media user commented: ‘Another one for prison. Hope you have fun with your new inmate friends’, to which Smith replied: ‘I LOOKED IN THE CELL NEXT TO ME AND ITS THE ICE CREAM GIRL.’
Another commented: “I don’t like the feds but god I hope they get you”.
But when one person asked “has anyone reported this degenerate to the @US_FDA [US Food and Drug Administration] yet?” a defiant Smith tweeted, “do it, baby, I know the law”.
A friend of Smith’s, a YouTuber named Larz, claimed on Twitter: ‘I started the trend of opening products without buying them.’
Walmart said in a statement to DailyMail.com: “We are investigating this incident.
“If someone tampers with a product and leaves it on the shelf, we will work with law enforcement to identify and prosecute those found responsible to the fullest extent of the law.”
The incident was reminding us of a recent incident happened a few days ago, at a Walmart supermarket in Texas when a teenage girl was caught on camera licking a tub of ice cream before putting it back in the freezer.
Police said, the teenager could face charges of tampering with a consumer product, which can come with a prison term of up to 20 years, and a $10,000 fine.
