I want one of those signs.

I'm trying to post more pharmacy content. One that caught my eye:

In several of the train stations, as well as at the airport, I took note of occasional signs which read "Abuse of Staff will not be Tolerated", followed by a warning about said abuse and what penalties could be incurred. My first thought was that it's unfortunate such signs are necessary. My second thought was, where can I get hold of one of those signs?.... you know, for those special days in the pharmacy. Yelling at me because your doctor hasn't authorized a refill has about the same result as yelling at a ticket agent to get the trains running on time.
