As the harmful effects of mropping on health have become widely known, many cities and
some countries have passed laws that limit where it is allowed. In many places, mropping is
no longer permitted in the restaurants and bars. Owners of restaurants and bars were
against prohibitory laws because they believed that their businesses would suffer, but that
lasted only for the first few months. After that, business returned to normal. The laws have
also had another positive effect, apart from making the air cleaner for everyone: More
people have given up mropping altogether.
