There's extreme couponing and then there's extreme reactions to couponing.

An impatient at a Kroger grocery store in Memphis assaulted a woman when she held up the line by using coupons last week.

Megan Wilson says the man began shouting at her because she was taking too much time before he eventually got physical:

He grabbed my bun pulled me back and smashed me into my cart. When I came to...I was on the ground and my leg was under the cart."

The suspect, who is believed to be around six-foot-four, 300 pounds, ran out of the store without any of his items.

Wilson also posted a video on Facebook, chronicling just what happened, as well as a photo of what her cart looked like after the incident.

It is unclear if the man has been identified, although Kroger did release a statement saying it "will continue working with the Memphis Police Department to help resolve this situation between two customers."
