Even if businesses are closed, business owners can still go into places they own to look through mail, make sure everything is ok and in their case, make masks. Cynthia and Molly were working side by side when the pandemic started so I don’t see a problem with them continuing to be together. If they are not seeing customers then they are not putting others in jeopardy. People that work at grocery stores, hardware stores and restaurants are seeing other people on a daily basis. I actually have more of an issue with Tim and Veronica since I don’t believe they saw each other much before filming pillow talk.
