Ah, yes. I took money several times, and it made her furious. Every time, though, it was for the same reason. I tried very hard to pick my battles, and I think I did a good job tolerating and ignoring her bedroom clutter and dust. Filth, however, was a different deal. I'll not even name up all the stuff I found in there, but it was including and beyond food "remains."
I'd ask and warn several times but then finally just do it myself. I kept telling her that maid service was d___ed expensive, which was why I didn't have one. They seem to never learn from the past though, do they? After a few times, one would think it would be predictable that I'd get fed up after a point, provide "maid" service, and take "her" money.
I guess the next time an appliance comes up missing, you could take the money to replace it and give difficult child a nice photo of the new, updated appliance you buy for yourself.
