I worked hard to find a tenant for this commercial unit and finally found a guy to open a used appliance store. He made improvements to the unit for two months and was just about to open when the place was raided by cops at 4 am. Turns out the store was just a front and the REAL business was in the basement where he was making moonshine. Here is all that remains of his still.

Apparently clean conditions are not necessary for making liquor.
