I have found recently a few places, shops, pubs, restaurants that offer a 10% discount for veterans. Despite showing a photo of me in uniform by my aircraft, this wasn't accepted. So maybe there is a use for a 'Veterans card'.
I acquired a veterans card via RAFA. I don't use it in this country but in the USA it is like gold.
Walk into coffee shop "Free coffee for our forces and veterans" I said how about allies?" flashing my card. "Thank you for your service sir - here's your coffee".
