Think about the fact that these grocery stores, for the most part, took action to keep from spreading this virus quite soon after it was found to be necessary. Disinfecting and keeping the personal protected so they wouldn't be infected. Even then they weren't without issue as you say.
Not in PA they didn't... It wasn't until the middle of the 1st week of April that most locally finally closed the Salad Bars. After that, a few put up the plastic checkout barriers... but most cashiers didn't have masks or cloves. Even when the biggest chain in the area "Giant", put 1-way lines on the floor and closed isles when shelves were being stocked... the cashiers still did NOT have masks or gloves. They "touched" every single plastic, tin, glass, cardboard package each customer presented to them. They only started wearing masks & gloves this Monday after everyone in the State was forced to wear one by Wolf.
To date only the local Wies grocery store has reported an employee Covid case... and they were a shelf stocker. Granted the cashiers have been spraying down the conveyor belt for weeks... but with bare hands & no mask. Many are old ladies... you'd think they should have been dropping like flies, but they're still living... and working.
Where I think it will get interesting, is when dentists, pedicures & message parlors reopen.
