I'd have thought most people who really travel for business on a regular basis in First and Business would have long grown out of 'Look at me in my suit, I'm in First you know' and instead dress smart-casual. Which is exactly what those meeting them at the other end would expect them to do.
I mean seriously, who sits on a long haul flight wearing a suit? Fair enough for a 90 minute flight to Paris but long haul? Why would you possibly do that unless you were some sort of newbie who thought it was the done thing?
I suspect Firestar once got lucky with a Business class seat, suited himself up to the max and borrowed a Rolex and now thinks he's awesome, pitying the vagrants
