My maid is nice to my BB and our whole family. I will give her $200 Lai See and a T-shirt for her b-day. Last time, before her daughter's b-day, I bought a dress and some hair clips (altogether $200) for her daughter in Filipine, she was so happy with tears in her eyes.
The first year I gave her $500 lei see because I was not in HK almost the whole year and she was great to my baby. And the second and third year I buy her gold accessories around $500. I don't give her cash anymore because if she have money she lend to her relatives. Recently I found out she borrowed money from her friend to lend to her aunt for daughter's wedding.
