In April 2020, we didn't know that much about COVID-19.

I am still masking up indoors, and not staying indoors too long. There's just not enough people vaccinated and immunized yet. I'll take that small improvement in odds that masks seem to bring.

I totally understand why people don't want to work for minimum wage in a hot kitchen. They workers are a mix of young and old, meaning a lot of unvaccinated people. All together, for hours, in a small space.
