Most of us know that Singapore is a very clean country. There are laws to help keep it that way like no littering and gum chewing.
In a country so clean you should expect people to know how to wash their hands. I was definitely surprised to see these signs in multiple places. One thing I did learn (from the sign above) was that you can reduce your germ count by up to 99%. To accomplish this you need to wash your hands for 30 seconds with soap and water.
