Worker at SF's Zuni Cafe hailed a hero for helping to save the life of a customer

A busser at SF's renowned Zuni Cafe helped save the life of a customer who suffered from a cardiac arrest. He says he used the CPR skills he learned years ago in Argentina and Spain as a life guard and CPR instructor. The customer survived and returned to the restaurant days later to personally thank the worker for saving his life. The San Francisco Fire Department plans to honor the busser with a plaque, saying it's "well-deserved."
