"你係主人, 你叫佢坐低傾續約問題是天經地義的"
You are the one who talk first anyway, or you can pass her to Agency to talk about this.
Honestly, a "perfect" maid should be polite & able to finish all her duties. If you look for a new one, maybe she can't even do her job duties in a right way, u may get even more angry!
Most bun bun are smart but stupid to deal with "communciation" & "respect of Mum". I have the same case happen this week, I mad at her cos' she don't say "Yes, Mum"................. at the end, I talk with her for an hour, send her to agency to let her learn more about "how her employer think". Then, it is fine now.
As long as she can handle her duties well, spending some time with her for communciation is important.
