I have a problem with the response, “No problem.”
My old fashioned values have me believing that “You’re welcome” or “My pleasure” is the most gracious way to answer “Thank you.”
For a long time I figured it was my somewhat overzealous ideals about manners that had me cringing whenever I hear it. One of my favorite colleagues says it so I really had to let go.
Then a few weeks ago a friend ranted about it at a gathering. Most of the people in the group agreed. I was vindicated!
