Common Courtesy #1
I've noticed this a lot on pundit shows and it is driving me slowly mad.
OK, kids, pop quiz! How do you respond to someone when they say "Thank you"?
A. Thank you.
B. No, thank you.
C. My pleasure.
D. You're welcome.
E. None of the above.
Time's up! Pencils down!
Give up? Can't decide?
There are two correct answers: C and D.
Never thank someone who is in the act of thanking you. I know that it sounds like a nice reciprocal gesture, but all you have done is negated their expression of gratitude. "No, thank you" is kind of like saying "Fuck you! My expression of gratitude is far more important than your expression of gratitude. In fact, it's so important that I am going to make sure I get the last word in this exchange."
I prefer to use "My pleasure" in more personal and/or intimate situations. "You're welcome" is always the most polite way to go.
