This is the moment a fight broke out at a grocery store after a woman held up the checkout line for 20 minutes with her carefully organized binder filled with coupons.

Megan Wilson claims a man yelled at her and called her a 'junkie' for taking too long at the Poplar Plaza Kroger in Memphis, Tennessee on Friday.

She later took to Facebook, saying he grabbed the 'back of the head and smashed [her] face into the cart' after she accidentally spilled a drink on him.

But police released surveillance footage of the incident, and it appears as if Wilson purposefully dumped the contents of her drink on him.

Wilson posted a lengthy video on Facebook sharing her side of the story, and told WREG she spent 20 minutes with her special binder filled with coupons.

She said: 'I do carry a binder with a filing system in it. And then I usually also have a duffle bag or a large purse-type bag that I carry full inserts and things like that in.'

She claims a man complained that she was taking too long before he started making barbed comments calling her a drug addict.

Wilson said she was bothered by his words, and even said at one point: 'I really wanted to hurt the guy but, you know, he's three times my size.'

While Wilson claims that she accidentally spilled her drink on the man as she was leaving the store, it appears she purposefully flung it at him.

The man can then be seen moving towards her, although most of fight takes place outside the frame of the surveillance camera.

Wilson claims he grabbed her by the head and hit it against her shopping car.

She said: 'Everything kind of went black for a minute and when I came to, I was on the ground.

'So I stumbled to get up and the floor was slippery because obviously when he hit me, my drink went everywhere.'

She shared a photograph of her shopping cart, which toppled over in the scuffle, and police said she had a small scratch on her forehead.

Wilson, however, claimed much more serious injuries, telling WREG her rib might be cracked on top of a strained hip and bruised head.
