This made the women extremely angry and they reportedly started honking their vehicle horn and banging on the drive-thru window before eventually forcing it open and climbing through it.
The altercation came about when the two girls complained that they'd never received the Chicken McNuggets they'd ordered and paid for - but instead of then receiving them, the server showed them a receipt proving they weren't on their order.
"McDonalds can be a pretty weird fast food place", said a woman named Jennifer who only gave her first name, "it's kind of like a Walmart for fast food".
The moment was captured at an Indianapolis McDonald's in the early hours of Friday morning (local time) by Monique McNeely, the woman in the auto behind them.
The woman who shot the video, Monique McNeely, said she has been getting calls from as far away as New Zealand about the story. "That would really freak me out,".
According to RTV6 the manager told the women to "have a nice day" before turning his back on them to fulfill other customer orders.
"All I knew was I had to just keep on rolling and keep on shooting that video because it was going to help the individuals inside especially that last bit of video because that's when I captured the license plate number", she said. They shout and throw punches at the restaurant manager, them climb out and take off.
McNeely said she had no idea what the fight was about at the time and couldn't believe it was over chicken nuggets.
Thankfully, the manager escaped the incident unscathed, but the women did manage to knock over a pot of tea and break the tablet register. The store manager was not injured.
Video of the event was turned over to police and can be seen above.
