Not all the bothersome problems have quick fixes or answers, but I think this page will shed light on some possible solutions. What really bugs me is when people wear brown belts with black shoes, or vice versa. I do not know where these people are from. I see mostly men, but females are probely equally guilty of this outrage. Not washing your hands after using the bath room.
Men are the enemy here.
Wash those hands. I do not want to have to shack your hand or use a slat shaker, after you have handled Mr. Wiggley. And do not forget soap, water will not do alone, but it is a start.
