I did that one time this summer and I got a written warning because I was not watering my lawn on the designated day during the summer when my town sometimes has "water sprinkling policies". Basically if your address is an even number, you can water on even days and vice versa.
I tried explaining to the guy that I'm brewing and I'd just have to dump it down the drain then and would be wasting water which is kind of the whole purpose of the water policy. He told me he was just doing his job. It was kind of weird though that he was doing his job on a Saturday afternoon driving around with his wife in his town issued work truck.
I went online later that night to the town's website because I hadn't seen any signs posted and found out the Sprinkler Policy went into effect 5 PM the day before. It hadn't even been 24 hrs yet! So to this day, because of that moron, I waste water if its an odd numbered day because this code monkey will come back and hand me a $100 dollar fine for a second time offense and a $200 fine and a termination of water services for a third offense.
