Germaphobes, Stay Away!
Light switches are the most commonly touched surface in the bathrooms. Hence, there is every chance of germs sticking to them. When the cover of a switch is made up of coffee beans, all sticking to each other, the crevices can be a perfect hiding place for germs. Disinfecting them is almost impossible.
In all probability, germaphobes would like to finish their business in the dark. Even if someone is not a germaphobe, the gross design of this cover can turn them off before they turn the switch on.
