Engineering vs. Sales
then there is the "engineer" (I have yet to find out exactly where he got his education or in what discipline) turned Sales guy (which just happens to be MY BOSS!) that quotes a job for less than the materials cost (BY MORE THAN HALF!) and gets all pissed off when I tell him that he should have consulted with somebody that actually had a clue before he quoted a price to the customer.... and people wonder why engineers hate salespeople.....
