Working a 17-hour shift on a Sunday and still taking the time to pay attention to an elderly customer's needs may have been an ordinary day's work for Megan King, but her customer felt differently. The note left by the elderly lady overwhelmed the waitress: "Thank you very much for your kind service. This was my first time eating out alone since my husband passed. I was hoping I could get through it." King recalled that she had stopped by the lady's table for a small chat, since she looked a little sad, but had not realized that her attentiveness would affect someone so deeply. The fact that her tweet has fetched more than 600,000 likes shows the viral impact of seemingly simple acts of kindness.
