Need some help. I have been unable to determine which of my employees seems to be unable to get all of their used toilet paper into the toilet. At least once or twice a week there is a small piece of crap-covered toilet paper on the floor in the men's washroom. This usually small piece of paper always includes the partial impression of a shoe tread.

No, I have not been able to match the tread to an employee's shoe. Yes, I am desperate enough to have tried. This has been going on for six years!

I honestly believe that this is not an intentional act, but rather the result of an unimaginably poor wiping technique. This does not excuse the fact that they have not shown the courtesy to pick up this leftover paperwork.

I would immediately terminate this employee if I could determine who it was. But since I don’t know who it is, the best result would be to educate the employee on a more hygienic wiping technique without me ever having to put a face to the poop. I have, unfortunately, been unable to find any type of sign or poster that provides wiping instructions that I could hang in the washroom (hopefully temporarily) until the lesson is absorbed. Any links to such or any other ideas would be appreciated.
