A tired mother came in with her two children asking for leftover food, so I served them hot meals and desserts instead.
Before leaving, she secretly left a check covering a month of restaurant supplies, with a note praising my kindness.
Three days later, she returned elegantly dressed and revealed she was a famous social media personality who tests how people treat those in need.
My boss gave me a raise, but the greatest reward was knowing my simple act of kindness had touched someone deeply.
