OXFORD (CBS) —A week ago, two men were on opposite sides of a legal battle but on Saturday, a crowd of veterans in Oxford accepted an apology.

“I was very uneducated about PTSD. I had no idea the effects it had on your life,” Russell Ireland told the crowd.

Ireland says he’s received death threats and calls from around the country after he kicked James Glaser and his service dog out of his Big I’s Diner.

Glaser is an Iraq war veteran who suffers from Post Traumatic Stress Disorder.

Last week, Ireland refused to serve Glaser, saying he didn’t need a dog for emotional support.

Since then, customers have been boycotting his restaurant.

“I stand here embarrassed. Ashamed. I ask for forgiveness. That’s all,” Ireland said.

Glaser and dozens of veterans used the opportunity to raise awareness on the everyday challenges veterans face.

“Not just for PTSD, but service dogs of all kids; diabetic, seizure. You can’t see that stuff. You can’t see PTSD. These people, really want to live their lives in this United States,” Glaser said.
