2/11/2021 Face Coverings – Business Owner Guidance
Businesses are required to follow the face covering requirements for specific activities as provided in the guidelines: https://www.governor.wa.gov/is....sues/issues/covid-19 The following information provides additional clarification for
businesses on the interactions with customers who are not wearing a face covering as required.
...

2. If a customer enters a business without wearing a face covering, the business must engage with the customer to ensure the customer is
*** aware of the face covering requirement ***

and to ask if the customer is exempt from wearing a face covering as required pursuant to Proclamation 20-25.12.

3. If the customer responds ***stating*** s/he is exempt under the requirements, the business may:
a. Offer a reasonable accommodation (alternative way to receive service, if feasible). If the reasonable accommodation is
***refused, [the business may] deny the person entry; or
***b. Allow the customer to enter.

4. If the customer responds stating s/he ***refuses to wear a face covering (not exempt under the proclamation but unwilling to wear a face covering), the business ***must deny the customer
entry/service (unless there are worker safety concerns). The business may choose to offer an alternative way to receive service, when feasible; however, if the alternative is refused, the business must deny entry as provided above.

5. Businesses are not required to directly engage with customers if there is a fear of or reason to believe there is a threat to worker safety.

Bottom line. Businesses can choose to allow you to enter if you have a medical exemption, which you tell the door guard. At that point, the business has a choice to either offer alternative accommodations, or to allow you to enter.

But, if you simply refuse REFUSE to wear a mask and do NOT have a medical exemption, the business MUST refuse to allow you in, and may offer alternatives, but are not required to provide you service.
