You would prefer your maid to address you as "Ma'am", or calling your name?

I have never had any maids. But I think it depends on your relationship with them. I personally wouldn't prefer to be called ma'am or madam even if I'm not close with her. But I know people who strictly prefer their helpers to call them Ma'am. Their justification is they don't want the helper to cross the line. I stay with my in-laws and a part time helper comes once or twice a month. She calls me sister and I call her Aunty (as she is around my mum's elder sister's age)
