I read it as people shopping, not people that work there. So folks who are out-and-about, but are not in the more likely to have it groups (healthcare workers or people working at the grocery store). You're right about older and sick people.
- cm2187 7y agoNo that's what I meant. People shopping and therefore not at work. Therefore intuitively I would expect the population tested to be less contaminated than the population not tested (because at work).
