nice message with the real reason for the ashtrays.

one thing that bothered me however, was that push vs pull handle design. if you're really trying to provide affordance, why have a handle at all on a door that needs to be pushed? isnt it our natural tendency to pull on a door handle when provided with one?

all we'd need was a "Push" sign and we'd be done. The shape of the handle hinting how to use it seems subtler than providing the whole door surface as actionable; and if you had to unlock to open, we have well established pushable door designs already.
