At the pub. He's bringing examples of his design work, I'm taking him a dodgy schematic to critique. My boss, Stinky Doug, will be doing the money interview later if the chap passes the technical chat.

I am not, for reference, going to ask him whether Batman or Superman would win in a fight.
Be your own evil twin.
