I digress-but- I once cleaned for a lady with a DH with dodgy heart so I went in once week when she went to hairdresser (think I was actually babysitter in case he had an episode, but she never actually said that!) Anyways. I used to do 2hours in 3bed. Bungalow and do all windows alternative weeks. I was very thorough and cleaned as I did my own home. However, she annoyed me by sprinkling talc on top of cupboards and high places, and would scatter a load of dressmaker pins under the sofa and chairs, put jewellery under the beds to obvs. Check I was doing what I should!! I went along with this until she left quite a sum of cash sticking out of a tallboy drawer and I thought " she's gotta be kidding me, that's it!!!!!" So I gathered all the dross she left including the wad, after finishing my clean, and dumped in in the middle of her dining table together with the contents of the hoover bag (that long ago) took my fee and left a note saying I thought she'd like to see what I'd found and wondered if she realised someone was leaving stuff under beds etc and maybe her DH was getting a bit senile? Never went back , she saw me frequently as lived round corner and looked ever so embarrassed whenever we locked eyes. Cheek!
