Not to mention roadside stalls, I used to work in KFC, where the requirements were very strict and actually very hygienic. Then, one day, a girl told me that KFC was dirty. I was particularly surprised. I said no, I work there. I wash my hands whenever I touch dirty things, and I have to wear work clothes. As a result, she said that her sister also worked in KFC. After going to the toilet, she gave people hamburgers without washing her hands. Hamburg fell to the ground, picked it up and sold it. However, I was dumbfounded. So, what I want to say is that whether a place where food is cooked is dirty or not depends entirely on people's personality. If most people think it's unconscionable money, they won't do to others what they don't want them to do, so we can't do that immoral thing. But some people don't think about it.
