I think what is more interesting is that to spend $800 on Scotch he must be accepting his military pension. Someone mentioned you are not entitled to one unless you serve 20 in the USA, but remember he saw active service and in the UK, at least, a war pension is a ruddy good dollop of cash. I guess theyll just say "take caeser's money if you are entitled" but this is from the MOD and hes gods spokeman.
I couldnt give a fig about the scotch, jws drink, after all, but i do think (ok im assuming) its interesting he probably lives off a military pension.
