Many years back I had a house cleaning business and commercial cleaning business. While it was a profitable under taking, it did come with many pit falls.
One large commercial contract that we cleaned nightly had this Magpie that was the unit Manager, or better known as the Keeper of the Cube Farm. About once a week I was summoned to the building to meet with the Facility Director to address her complaints. One time it may have been her accusing one of my girls of taking a piece of candy off of her desk, another time it may have been a complaint of not vacuuming good enough beneath her desk. It became a game of Cat & Mouse. She would intentionally try to set us up.
One week she complained that there was a dead cock roach far beneath her desk. Oddly enough, there were never any roaches found elsewhere in the 30,000 square foot building. The week following the coach roach incident, I decided to make my rounds and conduct an inspection of the entire building with an emphasis on her Cube Farm and her Cube in particular. There it was...the smoking gun. Tucked neatly in the back of her cube panel was a shiny newly minted Quarter.
After finding the quarter I decided to conduct an experiment. Instead of placing the quarter on her desk with a note, I simply picked it up and laid down two dimes and a shiny nickel. I never heard a peep out of her for the remainder of our contract.
