No there isn't. A salute by memebrs of the armed forces is in recognition of the fact the holder has a Queens Commision. Therefore respect doesn't come into it. You'r saluting the commission not the man.
(Which is quite lucky as most oficers deserve a completly different type of salute)
If you want to show respect etc, then chuck some money in a Help4Heroes tin, buy your poppy in November, don't stare at us when we walk in uniform, and the most important thing DON'T VOTE LABOUR!!!!
Oh and if you want, I'll have a pint of John Smiths lol
