The dumbasses at Walmart changed the entry and exit points at the Super Walmart’s here in Texas. Entry was at one end, rope barriers directing people in through one automated door. You had to leave from the far end of the building, again through double automated doors.
People do dumb things, and many people would stop once inside at this bottleneck and ask directions. Could you create such a cluster where infection could spread any easier if not by design?
The local Walmart I shop at on occasion doesn't do this. My beef with them is they don't have any hand sanitizer stations at the store exits. They can afford it.....
