Weirdest sign at a convenience store I ever saw.

When on vacation in Florida I walked into a store to get a cup of coffee and I saw a sign on the microwave that read "Only for food use, Do not heat Urine'.

Apparently people have been going into this store an heating their urine in the microwave because theirs a drug clinic near by and they want the urine to be warm so it seems they just peed in a cup.

The reason the sign had to be put up is because a woman was heating her urine in the microwave and the owner came over and asked to 'quit heating your urine in out microwave'. The woman responded 'I don't see a sign that says I can't heat urine in the microwave'. So the owner had to put up a sign. (and my eyes are rolling in the back of head)
