Everyone knows that washing your hands before touching food and silverware is an effective way to prevent all kinds of sickness. Did you know that the menus at a restaurant are one of the dirtiest things in the building? Menus get touched by tons of people every day, and restaurant employees usually only disinfect them at the end of the day -- at the most. Once you’ve ordered, use the restroom to wash your hands thoroughly (hot soap and water) for 30 seconds before touching your food.
