A woman on TikTok has shared a personal story about how a "pay-it-forward" chain at a Taco Bell reportedly led to a heated moment in the drive-thru line.

Meredith Donovan, a content creator, turned to the video-sharing app on Wednesday, Aug. 9, claiming her $60 Taco Bell order infuriated the customer in front of her enough to cause a scene at the drive-thru.

"The car in front of me pulls up to the pay window. I’m on my phone, and I just hear a car door slam," Donovan recalled when sharing the story with her TikTok followers.

"I look up and this lady gets out of it – has gotten out of her car in front of me – and is running towards my car screaming her head off," she continued. "I couldn’t make out what she was saying at first, so I rolled up my windows and I locked the door cause I was scared."

Donovon said she eventually realized what had upset the woman because she could still hear the customer screaming, despite her car windows being closed.

"I heard, ‘Scam,’" Donovan noted.

It turned out that the woman was upset because a pay-it-forward chain had been started at the Taco Bell drive-thru by a prior customer, according to Donovan.

"Basically, the car before her paid for her meal," said Donovan. "So, she was [going to] be a good person and pay for the car behind her."

"You know, a pay-it-forward scam," Donovan said in her video, though it’s not clear if Donovan was initiating sarcasm.

Fox News Digital reached out to Donovan for comment.

The "pay-it-forward" chain initiates when a customer alerts fast food workers in the drive-thru window that he or she is offering to pay for the food ordered by the customer who is in line behind them. The chain may or may not continue, depending on if one driver refuses to "pay-it-forward."

Donovan said in her video that there was a mix-up of cars in the drive-thru lane. This led to Taco Bell employees to present Donovan’s "expensive order" to the woman who was reportedly angered by the amount, Donovan explained.

"That's the chance u take when u do it," one TikTok user pointed out in reference to Donovan’s expensive order and the reported customer’s reaction.

"People are wild. I'm not paying for no one’s food," another TikTok wrote. "[I don’t care] who you are."

"Some people are nicer than you," a TikTok user replied to the comment.

"If I'm paying for it then in taking it. Y’all can pay for whoever's food/bills but I sure won't. Guess I'm evil," the original commenter fired back.

Fox News Digital and FOX Business have covered the rise of pay-it-forward chains at fast food establishments in recent years.

The chain is usually ended when a customer tells the cashier he or she doesn’t feel comfortable paying for another person’s order. 

Social media posts shared by chain breakers often cite expensive orders from customers’ behind them as the reason for ending the pay-it-forward chain.
