I lived closer to WinCo in DFW area and could walk to a grocery store to buy bread or some random grocery item. It was really nice. I don't think Europeans will ever understand how much of a flex it is to be able to walk to a grocery store in Texas.
instead of them being on every corner.
They are saying almost no one in Texas can walk to a grocery store. Hence, it is a flex if you can. And Europeans don't understand that it is that unusual.
