Seven calls into my working week and already five of them have demonstrated the First Rule of Tech Support: "Never trust the customer's assesment of the problem." Because for every person who does, in fact, know what they're talking about, there's twenty who see "Please enter your product key code" and then call claiming they need to acticvate their desktop software. (No, you need to enter your damned product key code.)
And this is why, a lot of the time, my job could be done by a recording of me going "What error message are you getting? Sir, please could you read me out exactly what it says on the screen? Sir, please just read me the error message." Augh! (And this is how you tell the people who know what they're talking about from the rest, because they will at best start out by telling you the error message, and at worst only need to be asked to do so once. And they know how to bloody well follow directions. "Okay, so select UK there and press OK." "It says Alpine Ski Region, press OK?" "... No."
I love my job, I love my job, I love my job, ...
