how do muslims clean their bums after poop - what do restaurants use to sanitize dishes

It was not until recently when I was traveling to Tunisia that I realized that Muslims would not clean their ass with toilet paper after poop.
Instead, they wash with their left hand, usually a bidet or kettle, with clear water.
That's why in Muslim toilets there is a pot of water on the top of the tank in each toilet compartment.
Arab countries, India and North Africa have this habit.
In many Asian countries, people use sit-down, crouching systems, which are usually sprayed with spices after the business is over.
Therefore, a special tip for traveling to these countries is: always put some toilet paper in your bag and some toilet paper in the line Li.
As long as my hand is not in direct contact with my back, I don't mind spraying my ass with water and then drying it with toilet paper.
The problem is, I found that the direction of the injection did not point to the anal area.
It is very difficult to put yourself on the water jet so that the water will reach the desired area.
Another problem is the water temperature.
Once my sensitive area was burned when I opened the bidet.
I remember the last time I left the temperature control in a comfortable place!
Left or right this is why Muslims never eat with their left hand when shaking hands, and do not distribute.
They do not greet or shake hands with their left hand.
This is considered disgusting and rude.
When you eat with them, it's a good idea to plug your left hand under your thigh.
The right hand is used to wear clothes and shoes, enter the mosque, shake hands and other noble undertakings, and the left hand is used for dirty work such as blowing nose.
