I only saw this for the first time over the weekend when I was interstate - the Kmart I went to seemed quite nice and refurbished, however the checkouts were right in the middle of the store
I thought this might have been a one-off new store type thing, but I've since seen people complaining about the impracticality of this setup on social media. Apparently a number of Kmarts now have this arrangement. It's a thing.
The biggest complaint seems to be having to line up when you get to the exit to show your receipt/purchases. I guess people have already lined up to pay, so they're annoyed about lining up a second time.
Does it bug you, or are you not even mad?
