Exactly what kind of shit can cause Walmart to shut down due to plumbing problem?

They should be careful from now on. No more McDonalds or Pizza. Bring homemade salad to work.

#wacktheory says radioactive tampon contamination or toilet methlabs.

...the sort of secret stock shit info that needs to be anally withheld from the markets in case the walton family's heap of platinum-plated turds gets flushed.

Seems like the shit is so toxic that the did not even hire a plumber nor get a repair permit yet.
