I'll tell you my experience. I have hired an Indo maid whowas introduced by my auntie's maid. She is her sister. I also think like you in the beginning. However, when my maid come, she has created lots of trouble to me and my auntie. She is a big liar, always tell lies to my aunt how our family treat her ( which is not true indeed) and create lots ofg rumours to my family. I would swear that I will never hire any maid who know my family and friends.
