I noticed in a hotel I stayed in recently that the same sort of things were posted. Again california.
p.s. since we couldn't smoke in the rooms, my brother0in-law and I decided to grab a couple of cigars and head down to union square (we were in SF) we lit them up and were enjoying them thoroughly in the middle of the night, when some guy comes up and talks to us. As he was talking, he asked if he could have a puff on our cigars. We both told him "no" so he grabbed the one out of my brother-in-laws mouth, took a drag and walked away. Being as the guy was a little crazy, we let him go, but man was it a bummer.
