How do you not drip back onto it? Do you use paper too? How is it okay for me to use the same one right after Typhoid Larry? Doesn't poo go everywhere?
If someone was preparing food for you, would you be satisfied if you saw them go to the toilet and then just wipe their hands with a piece of paper instead of washing their hands?
This is where some cultures got their thing about not using the left hand to shake or eat food with. The assumption is everyone cleans their butt with the left hand. Little do they know I'm a righty.
