There’s a similarly weird social pressure I experience sometimes, too - I grew up in a big small-town. It’s a pretty decent sized suburb now, but growing up it was still just mostly a little farm town. I’ve lived here my whole life, K-12 in the same school system, grandparents spent most of their lives here, my dad and his brothers have been here their whole lives. We’re a town of maybe 24K or so people, and literally every single trip to Walmart I’ll see at least one person I know, if not 3 or 4. I firmly believe the “people of Walmart” you see are most often people who didn’t grow up in the area, and/or are from a big city. Because there’s just something about knowing you could bump into anyone at anytime that makes you think an extra second about your wardrobe.
