| Re: Stupid, stupid, stupid and pointless composition of public messages I would imagine, it's so you dont upset the patients by shouting 'Fire! We're all going to die!'
Similarly, if you're an actor on stage at a theatre and you spot a fire,you have to say something like 'duplicitous chips' or some other phrase that wouldnt commonly be heard in your lines, so as to alert others backstage but not necessarily alarm the audience, should it be something controllable that they need not know about. |
