I’ve only been to a casino once in my life. Perhaps fittingly for this story, it was during a business trip to Barcelona with life assurance company NPI, at the very start of my career. I walked into the Casino de Barcelona with a colleague, watched a gentleman lose several thousand pesetas on a spin of the roulette wheel, and promptly walked back out again, feeling a little nauseous at the speed and scale of the loss. James Bond, I’m not.
