Man tries to create a disturbance in Walmart, but a bystander puts a stop to it

An unruly man came into Walmart and began turning things out. He got to the checkout line and started acting aggressively. As a result, people in the store began trying to calm him down, to no avail. The man kept acting up and then he picked a fight with a man half his size. This little man put an end to all of this.
