from the Telegraph article that this seems to originate from

User Posted Link the parts of the guide that are actually quoted don't seem to make any reference to greetings at all, however, i can see where it might be necessary for police officers to be aware that one person's evening may not be the same as another's - though i guess police should also be dealing more in exact times anyway, particularly if trying to establish alibis and such s**t.
