We had some fun with a No Smoking sign with braille on a workshop door once.
When it was installed, we queried if they were aware that blind people do not smoke. They said -> ok, then they would know that someone was breaking a rule, since the signage was also in braille.
So then we asked them, do all doors require braille signs, or are we going to be required to point any blind people to the signage so they are aware it is there on the door.
They saw where this was going and ruined our fun.
We were told that engineers are idiots, the sign is there to stay, and if any blind people get anywhere near the workshop to please inform them immediately.
Your signs @dweiss look nicely done. Made a lot of people happy (or at least less lost).
