Definitely will give her lai see! I give lai see to all maids (my mum's, my brother's, my grandma's, my friend's one).
For my own maid (in the future), give $100x2. For friend's/relative's maids, $20x2 or $50x2
Not only maid, I also give to security guards too. I also gave to pantry ladies at my office when I was working, $50 each. Little $ can make everyone happy!
