Re: Client support, we've heard about it
It's not my job to ensure you want to continue doing yours ..
As a matter of fact, if you provide a support service of any kind (not just the IT), it is.
And most people in IT support I encounter are doing it very well - which, incidentally, means that they rarely if ever encounter impolite and irate users.
As you say, it is a two-way street, and it takes two people behaving unprofessionally to start a real kerfuffle.
