Crikey, you ungrateful bunch. You don’t have to have one; it isn’t compulsory!
Personally, if it affords me some form of recognition that I have served the country and that it might give me “a leg up” for extra help in the future when I need it, then I am most grateful. As it might bring me some other benefits and costs nothing when I have to change my photo licence every 10 years anyway, then I, for one, will most likely decide to have it.
Thank you
