Seriously?
Check it out:

A restroom at a Wal-Mart in eastern Indiana has been closed indefinitely after an employee discovered a working meth lab inside.

State police say a Wal-Mart employee alerted police after seeing a man he described as suspicious enter the restroom about 11:30 p.m. Thursday with a backpack and leave without it. The Star Press reports (http://bit.ly/18o9m0E ) that members of a state police meth suppression team removed the dangerous chemicals.
