Video showing a woman losing her temper over a service dog in a restaurant has burned up the internet. "You have an animal in a public restaurant!" the woman screams, pointing to an Army veteran and his Great Dane, a PTSD service dog. "It's disgusting to have an animal inside a public restaurant!" she shouts. Told that the dog is there to calm its owner, who served in the military, she yells "Congratulations! So what? It's still nasty to me." Tempers escalated as she argued with another patron.
