Have you every noticed that those posted signs, that say you must be polite or you will not get service, or / and security will be called, are ONLY in government offices in BC (or government funded offices)??
You would never see a sign like this at a building supply store ... department store ... restaurant ... car dealer etc. These kinds of signs only appear at places like offices for government services, and say hospital. ONLY at places you would be because there is something you really need.
So why are those signs there??
