It's an Australian supermarket - South Australia I'm guessing based on the "SA Lotteries" sign in one of the photos. The supermarket in question is a Foodland but could easily be any other supermarket in Australia. I thought it was my local Woolworths store based on the product layout in the photos and I'm in Sydney, NSW.
Makes sense. The title is still a bit of an overgeneralization.
Nice sleuthing! Foodland in SA is correct.
The post author seems to be in Australia, not the US.
