Depends on where I shop. I live in an area where most households don't live paycheck to paycheck. The supermarkets have an interesting dynamic now that many people work from home, in that there's time to take breaks during the middle of the day to go shop for groceries. I do that.
I guess the more interesting is at dollar stores. I can't resist a bargain, and some days they seem to be much busier. It's a bit more complicated because those living paycheck to paycheck will seek them out, and many actually work in service jobs in my more affluent area, along with those living in less expensive parts of my area. However, there used to be more options. Dollar Tree used to have three stores fairly close to me, and now it's down to one. And the irony is that the only one left is across the street from a Whole Foods location. Go fig.
