Using bad manners to get good manners

I have a pet hate (yes, another one). I understand it is polite to greet people when you see them. When I get to work I tend to politely call "Hi" to anyone I walk past or sit near to. And then I move on irrespective of whether my greeting gets a verbal response or a polite nod or smile. The interaction takes 5 seconds and all parties involved can move on with their lives. I may even be prone to nod or say Hi to anyone walking past my desk in the morning if our eyes meet. 

But some colleagues! some people! They have to have a verbal response from me when they greet me. They actually stand where they gave their greeting and wait for me to move my lips and vocal chords and say at full volume "Hello, How are you, It is good to see you today, have a good day". It is of no matter if I am currently on the phone or eating food or writing a proposal for World Peace or currently in a business related conversation. The Greeting Must Occur!! Worse, they actually raise their voice and issue a second greeting in impatience, usually starting with "Heellloo-ooh" or "I said Hello".

And the dirty looks! The look of rage that I made them wait an extra few seconds before singing a full response to their greeting.  The look that says they think I have no manners, and that I was not brought up proper. 

Seriously, do people have nothing better to do than demand the recognition that they were witnessed arriving at work? Your impatience is intrusive and offensive to my sense of politeness.

Now scoot!
