Annoying that they've blurred the guy's face out. Somebody could easily verify it by saying, actually that's Rear Admiral Dave who I served with in Gallipoli, but if he's guilty of being a dickhead then he doesn't deserve to have his identity protected.
A few years ago I got a loyalty card from Hotel Chocolat, and you could choose your own title from a large list - everything from Mr to Sir. I think Rear Admiral was one of them. I chose Commander, like James Bond.
