Tigs, you are a really, really nice man!
Some years ago, having arrived at Lyneham in an RNZAF Herc, five days out of New Zealand, and decided to take a chance on a train from Kings Cross to see my 'old man', and still in uniform with "Royal New Zealand Air Force" shoulder flashes [they just have "New Zealand "now], I bought a pint and was about to move to a seat when a well-dressed, well-spoken gentleman in a suit paid for the beer. "You chaps should never have to pay for beer here Old boy", and walked off!
