New Jersey resident Archie Fagan may have served in World War II, but the 90-year-old loves his job making customers smile at a local supermarket and has no plans to stop.

Fagan has been working at the ShopRite in Flemington since 1993, and he continues to put in 40 hours per week at the grocery store.

“I love what I do, where I’m at and who I am,” Fagan told ABC News. “I was born in this business as a child 90 years ago and I love this business and I love the people that I care about here and I love the products I sell and it was made for my lifetime.”

Fagan was drafted into the war out of high school at the age of 17, beginning his service in the army in June 1944. He was honorably discharged more than two years later after serving as an interrogator of German prisoners and fighting in the Battle of the Bulge, where he helped liberate the Dachau concentration camp.

Fagan was even called to duty as a military observer in the Nuremburg Trials in 1946.
