The phone call is a bad example of not able to deal with criticism. I admid Andreas does not find always the finest tone when he writes, but his comment ok and he is right in the message. To give good answers we need a clear picture of what one whats to do. And the best way to get a good answer, is to provide meaning full information right away. All of us have things to do and most of us is not in the mood in pulling the information out of the questioner. People react differently if a question is not ask the right way, most of the time I would ignore it if i don't have the time. Andreas responds but seems annoid of the fact that he has to ask for the missing information.
The good thing in that is, that the questionier has the opportunity to correct the situation and get good answers eventually. Even though some people might be afraid to answer again.
But let me make one thing clear, nothing justifies such a phone call!
