There's something to be said for being nice to people, even when they don't return the favor. Melina Salazar, a waitress in Brownsville, TX, will definitely tell you it's worth it. She kept a positive attitude and a smile on her face when dealing with her most loyal customer, 89-year old Walter "Buck" Swords, who she described as "kind of mean" and less than enjoyable to serve for nearly seven years. It turns out Walter appreciated Melina more than she thought, and left her $50,000 and a 2000 Buick when he passed away in July - no doubt the best tip she will ever get for serving hashbrowns.
