Working in retail is great for those who love interacting with people from all walks of life all day, every day, and good on them.

But all it takes is one problematic and entitled customer to ruin the shopping experience for all the other shoppers who just want to make their purchases and go about their day.

One 7-Eleven worker encountered such a customer but showed he had absolutely zero tolerance for rude behavior.

His verbal altercation with a female customer–who had allegedly raised a stink over the price of a soda–was caught on video, and it went viral for how he railed into her in an expletive-laden rant.

TikTok user @thatsyesi posted the viral clip showing the cashier becoming unhinged and then epically dismissing the customer by quickly assisting the next shopper in line with complete and calm professionalism.

The TikToker wrote in the caption:

"My brother sent me this video of a karen while he was working 😂😂which yo raggedy a** 😂karens stay tripping."

They added, "The lady got mad over her soda being $3 instead of $2 and yes she got her money back."

Warning: explicit language.

The videographer bounced back and forth between focusing on the two combatants in the store like in a tennis match.

At one point, the worker called the woman wearing a black tracksuit and sunglasses a "scallywag"–among other things–and instructed her to never "come to the mother-f'n register with your phone."

"Get the f'k out of here with your raggedy a**," he continued scolding her, adding, "B*tch, I’m trying to help your stupid a**, and you want to come up here with that bullsh*t."

TikTok viewers brought out the popcorn.

And the clip served as a reminder about customer etiquette to avoid being on the receiving end of this guy's wrath.

The clip ended with the employee immediately switching gears to help the next patiently-waiting customer in line with professional aplomb.
