I got to our TJ's about once a week, and it's always been as great and safe an experience as I'd like. Interestingly, I did find myself in a different Trader Joe's a few weeks back, and while equally cautious their safety precautions were still somewhat different than those at our local store. (For example: everyone checking out lined up snaking through the store, and when you reached the end they directed you to registers as they opened up, rather than have people line up, social distanced, in individual lanes, as they do at our local store). So I asked, and learned that apparently each store gets to set their own safety rules, at least to some extent, since I assume there must be some consistent requirements they all adhere to.
Anyway, I have not once been to TJ's this past year (!) and felt it teetering on the brink of chaos, as it's sometimes felt at more conventional supermarkets I've been to. So points for that, and if it means standing outside for five minutes, so be it. It beats the alternative.
