In Boaz, Alabama, a maintenance worker at Walmart made a startling discovery.
While inside the women's rest room he discovered pseudoephedrine pills and a plastic water bottle with residue in the bottom.
The police were contacted and Chief Terry Davis called it a one-pot 'shake and bake' type of lab.
Davis told WHNT news that he had never heard of a shake and bake meth lab inside a business before.
Police said it takes 15 to 30 minutes to make a low-caliber methamphetamine, but believed the pills were not from Walmart, but another pharmacy.
