I had a customer (a Phd scientist) just today call me and rip me a new one for selling him a $20k piece of equipment that was in his words "a $20k door stop." I sold him a lemon. So I sent over a technician to take a look. Funny thing was once he plugged the machine in, it worked just fine.
I can only imagine the call I'm going to get when he sees the bill for $750 to have someone plug in his machine.
Well, you know...phd="piled high & deep"...
I could fill pages with stories like that one.
One I remember right now: back in '87, I was working as a technician for Olympia, fixing electronic typewriters. One day, right when I got back from a customer visit, my boss told me the customer had complained that I had screwed up her machine.
So I went back there, just to have her thoroughly insult me when she opened the door, telling me I was an idiot, I didn't know what the hell I was doing, etc.
When I finally got to the machine and turned it on, I saw the carriage move all the way to the left (like it's supposed to), and then move back to the center, and, no matter what I did, it wouldn't move from there.
So I looked at her, liberated one margin, moved the carriage to the side, set a new margin, and repeated the process for the other margin. Guess what? All of a sudden, the machine was working again! Just so happen that one of her coworkers had pulled a prank on her, and she didn't have the brain to check before blaming others.
She was kind of embarrased afterwards...
