What's the best response for "thank you for your service"? I like to say this...

So for a long time I did not know what to say when someone said this to me. But finally I have the best thing to say that makes complete sense...

With a smile I say, "Thank YOU for paying your taxes"

Its comical and they always laugh, but also very true at the same time. I am a people person and this has opened so many door of opportunity for me. Feel free to use it and post your comments on what you normally say.
