Individuals are not recommended to use public toilets. Because it is a public area, there are many people coming and going, and there will be bacteria and cross-infection. I have come into contact with many toilets that go to public toilets, and I have to put several layers of paper towels on myself before I dare to use them. It's troublesome and wastes a lot of paper towels, so. It's better to squat in a public toilet.
