Our srtl/log lets us keep a bottle of water with us in the back. He has told us though that if Steri-tech comes they have to go. He also let it be known that if he ever found any empty water bottles laying around we would be be allowed to have it back there .Any "no water on hand" rule is something I will never enforce and gleefully break. I've had an ETL try to push that crap on us in the backroom one time. He changed his tune after he had to help us with CAFs when we had a couple of call ins.
