The current ETS standards for workplaces, including the requirement to wear PPE, needs to be revoked. Ongoing research is finding that COVID-19 is not spread in the airborne fashion one reported (see Washington Post article https://www.washingtonpost.com/nation/2020/09/21/cdc-covid-aerosols-airborne-guidelines/)
The permanent use of PPE will discourage customers from face-to-face business (it is hard to understand communication), create another expense (providing PPE), and will not make a measurable difference in combating the spread of the virus. Monitoring hand washing and sanitary surfaces is a more manageable, and as effective, method of controlling the spread.
