"Thanks!" "You're welcome."
The above acknowledging rejoinder seems to date back to the 19th century.
How about the edgier response, "No problem?"
Or: "Not a problem."
These I like.
"No problem" sometimes comes after a "thanks" for service or favor rendered, but implicitly, it's a sly reminder that many social interactions are "a problem."
Pretty funny when you think about it.
