COMPLETELY unhelpful local response:
One TJ’s in my area has longer lines (Chapel Hill), and once inside, people are rude and self centered about social distancing, choke points, flow of traffic, etc.
Another one, in Raleigh, is a larger store, has shorter or no lines, and people socially distance and are polite, wear masks, don’t crowd items.
I don’t live in either city, and frankly would have expected opposite outcomes in terms of who was more likely to observe safety protocols (CH store is very close to UNC Chapel Hill, which is definitely seeing covid patients and is also doing front line research.)
It’s a head scratcher, but reflects a larger trend in my area: it’s impossible to guess until you’re in a store.
Shorter answer though, lines are way less crazy at both stores, and items like flour are back in stock.
