Some (Re)assembly Required

Setup: the local Walmart just replaced all their cart corrals.

What’s wrong with this picture?

As nearly as I can tell, the installers permuted the railings; a simple three bit rotate-left-by-one operation would fix it.

Not much to my surprise, every single corral looks like that; either the instructions were wrong or, more likely, the installers never read the instructions. Obviously, they didn’t think about the results and nobody ever checked the final result.

Prediction: the corrals will look like that forevermore…
