Melina, a waitress at Luby’s restaurant in Brownsville, Texas, served the same grumpy old man for 7 years. Other waiters described Walter “Buck” Swords, an 89-year-old WWII veteran, as cranky, rude, and insulting. He was particular about his food and demanded that it be served piping hot. Melina never complained about his demeanor and always tried to serve him with a smile. Despite his attitude, Walter would always smile back.

One day Melina noticed Walter’s absence. Shortly thereafter she saw his name in the obituary section of the local newspaper. She was sad at his passing, and returned to her work. When a lawyer arrived the next week she couldn’t believe it. Walter had left her $50,000 and a car because she had always been so nice to him. She told her story in an interview with the local news.

Always remember to treat everyone with a smile, even if they don’t smile back. You never know how much your positive attitude can influence someone else’s life.
