A Hooters waitress at the Roswell, Ga., location by the name of Mariana Villarreal began making headlines after her extremely selfless deed hit the Internet—the young server donated one of her kidneys to longtime customer Don Thomas, who had lost both of his kidneys.
Thomas explained to the local NBC News affiliate,"Mariana had only been here a short time, I just barely knew her when she made the offer."
