A pizza deliveryman's customer service was on fire. Literally. Donatos Pizza driver Ralph Letner tells WDRB-TV in Kentucky that he was delivering a pizza to a mobile home park in Somerset when he saw a home on fire. Letner says he jumped out of his car and raced into the home to shut off the breaker. He found the homeowner and one other person inside, the AP reports. Homeowner Jesse Decker says Letner is a hero who saved his home and his life. Letner says his parents raised him to help people in need. He says he wasn't even supposed to be at work, but he had stayed past the end of his shift because it was busy. Firefighters say an electrical problem caused the fire. (More uplifting news stories.)
