I always stop for a bookstore. When I step through the door, I pause to take in the atmosphere and decide where to start browsing.
Here, the person politely requested I don a mask. There were free masks available. Everyone browsing turned to look at me. I said, “oh…that’s okay, thank you” and politely went back outside.
I would mask to browse books or when someone asked me to. But I wasn’t prepared to be put on the spot like that. It’s not what I go to bookstores for. :(
