That is correct and this happens in many, if not all, countries. In my country, health agents pass by from time to time and make health evaluations. When the premises do not comply with the minimum hygienic measures, they close them permanently or temporarily, as the case may be.
This is correct, although the Ministry of Health must function in the countries in order to carry out periodic evaluations in these sites, and thus take care of the health of the population. Although there will always be hidden sites without being evaluated, and for that reason caution should be taken when entering and leaving harmed.
For this to be feasible, you must offer a very good service in general, both in attention and hygiene, customers will arrive safely and the business will continue to grow.
