I'll bet the elevator people were vaccinated, so they could have let you on with minimal risk. In fact I bet you are vaccinated, so the risk would be so minimal as to be unworthy of a moment's thought. I'm finding it weird that people don't want to trust these vaccines. They are great vaccines, wonders of modern science. I was getting my hair cut yesterday and I bade the hair cutter take her mask off if she wished mentioning that I am vaccinated. She was grateful & told how it was making her face itch, she'd had it on so long. Turns out she's vaccinated too.
I find myself mentioning this frequently, that these are great medicines and we can afford to be more trusting.
