Yes, Walmart Shunning is a Thing
An unnamed woman pulled a stunt in a Wichita Falls, Texas, Walmart on June 25 that got her banned from the store, hopefully for life.
According to NBC News, Police Sgt. Harold McClure said a store employee reported that the woman had eaten half a cake from the bakery, then attempted to buy the other half (for half-price), saying she found the cake in that condition. While Walmart did not want to press charges, they did prohibit her from shopping at the store in the future -- a policy they’re familiar with, after an incident in January at another Wichita Falls Walmart. In that case, a woman rode an electric cart around the store’s parking lot while guzzling wine from a Pringles can. She was also Walmart-shunned.
Sadly, there’s a current craze to post unspeakable acts done in Walmart, for the sake of a little internet noteriety.
