I called and left a message for a dude, asking him to call me back with details about his "external exception error." He called me back about 10 minutes later and after I told him that I had some details on file he asked, "So do you have specific questions about anything or should I just unload all over you?" Must. Control. Snicker.
Every naughty comment alarm was blaring in my head. I managed to calmly suggest, "why don't you just give me a recap on the problems you've been seeing and we'll see what we can do for you."
