I take a call from a client who works in an airport. She has a paper jam in the office printer and straight away demands an engineer onsite yesterday! I get her to describe the problem and know straight away that if she follows my instructions I can have it back working normally in less than five minutes. She refuses to try anything and when I try explaining that I can have the printer working much quicker than an engineer can arrive if she works with me, she screams at the top of her voice and slams down the phone.
The scariest part of the whole thing to me was that she worked as an air traffic controller and got that freaked out by a simple paper jam!
