I also don't work for retired engineers or people who are going to watch over my shoulder all day. If somebody sells me a problem, let me deal with it my way. The time for customer contribution is in the design phase. Always check the blokes shed when doing a quote, if it has a peg board full of shiny tools, and vernier calipers, a vice and a tap and die set on the workbench then give the job a swerve.
There's a lot of truth in that, but I find them the most satisfying customers and those most willing to recommend you to friends.
