A woman named Megan Wilson was at a Kroger grocery store in Memphis on Friday and she was using a bunch of coupons. But it took a while, and a guy who was behind her in line started yelling at her. Megan yelled back . . . and eventually he pulled her hair and she fell over with her cart. The guy ran out of the store, and the cops are trying to track him down. https://twitter.com/beaver1003/status/809041484792078336
