Thanks for asking. A covid safe setting is one where mitigations are in place to contain the spread of covid. This includes but is not limited to: universal masking in n95/kn95 masks, sufficient ventilation and filtration of the air to reduce the virus floating around, limited time indoors to reduce exposure, workers staying home when ill. So, pretty simple things that have together reduce ones chances of getting covid.
Most places have not achieved this, or stopped doing so if they did. I’m glad you and you’re pharmacists mask, but that is bare minimum and sadly not a universal experience. Many people live in places where there is no masking from others and any requests for it are denied, even though that’s illegal under ADA. Masks are also just one tool that can be used to stop spread and should not be the primary method used.
