Sales People rely on us being daft
I have yet to meet a sales person that knows what they are taling about (with the exception of what might be written on the box).
For years I have been a computer application trainer who has put up with Sales people who sold training courses based on course outlines - as they knew naff all about the software applications themselves...but at the end of the day inevitably, their targets were more important than putting together a group of like-minded individuals in the same room on a suitable course.
Many a time have I found myself teaching a macros or advanced course with abilities ranging from "I've been on every course known to man and used the product for 6 years" to "i got a PC for the first time last month and my boss said it would be good to learn Macros".
As far as I was concerned, the only thing that kept those Salespeople in jobs was MY ability to somehow rectify an appalling situation by ensuring everyone got something out of the course - and subsequently came back for more.
Who gets the bonus for repeat sales? Not the trainer that's for sure.
It's just as bad if you go into a shop to buy a Video recorder (or such like). Whenever can the sales person answer anything about the product without reading the box first (as if I wasn't able to do that for myself!!!).
Sales people have been the bane of my life and are target, not Quality driven...hence I now work for myself, successfully, and many of them have long since gone out of business!!!
