@Tim: I’ll confess, I’m a trainee engineer, doing an apprenticeship at the moment. But doesn’t stop the engineer that’s being slowly released into the wild straining at the door 
But yes, I do still get mildly irritated by such folk Unless they are very good at their job – there are people on my apprenticeship I consider lesser engineers than many people I know with no such training. It’s all about mindset really.
@Annette: That is SO true! Lol, you’re more of an engineer than me at the moment
