When someone comes up to me and says "hello", I'm often inclined to ignore them.
Some people have told me that this is rude, and I'm meant to respond, but I can't grasp the need for this at all.
Do any other people tend to ignore 'friendly' greetings, etc.?
Have you considered the pre-emptive Klingon:
"NuqneH" = "What do you want?", "State your business."
The revelation comes when you realise social conventions don't have to make sense. They just represent the rules of an arbritary game. People who think playing the game is important will mark you down for not following "The rules". It is worth noting that in most places that covers the majority of the populace.
"How are you" "fine" is also a convention, a "Hailing frequencies open"sort of moment.
For convenience or courtesy the conventions may be observed. Occasionally it may serve to wake people up if the convention is deliberately subverted, but it's best not to do that by accident. The poor conventional creatures can't handle it.
My doctor reports that a fair proportion of people reply to HIS question of "How are you?" with "Fine", even though he wants to know, and they're there because they aren't.
