We have cleaning buddies that are supposed to sweep & mop the floor 2x/week to keep the dust down inside where I work. Today, they came around with a big dustmop for a broom and swept up most of the big chunks prior to the mopping. A 2″ screw was left calmly sitting where moments before it had been surrounded by other debris on the floor.
I asked NJ if he wanted to see something amusing. He did and he came over to my AO. I told him the story. He chuckled & said it would be funnier if I cordoned off the area and put a little caution cone or something.
You may guess from the language on the cone what is the principal language of los amigos limpianos. I took a photo and then, because even I am not that obnoxious, I picked up the screw, threw away the cone and barrer tape (both made from post-it notes) and went on about my day.
