She wanted to clean it and she washed it in the kitchen sink like you would wash a plate. I couldn't believe when I I saw it and she went on to reassure me she does it all the time at other customers houses and the piece of electrical is fine.
I told her that if it stops working I'll have to deduct it from her wage. AIBU? You wouldn't give the toaster a bath.
She's an excellent cleaner but could do with respecting boundaries a bit more. She'd previously water plants when I had just watered them and so some died, feed the cat, bin stuff that wasn't to be binned, ripped off a piece of wood from a floorboard and a few other things. I tell her after when something wasn't ok, but there is always something new and unexpected she does.
I'm always around and she never asks 'is it ok if...'.
