Several years back my mom, then in her mid-70s, read me an item in the New York Times’s Metropolitan Diary complaining about the use of “no problem.”
I pointed out that about a year earlier she had read me an item, also in the Metropolitan Diary, about the use of “no problem.” She dimly remembered when I brought it up.
I had some time on my hands and a couple of questions, so I looked it up. Turns out that this was the fourth complaint about “no problem” in the Metropolitan Diary column in…four years.
So, someone is complaining. Or someones. Also, the Metropolitan Diary editors have short memories.
I then did some research on Google Books, I think it was, to see if I could pin down the earliest use of “no problem” used in this context.* I worked my way back to the mid-nineties, I believe, and a novel by an American author in which the main character goes to rural Ireland and has a conversation with a very gregarious sixty-something postmistress. “Thank you for the stamps,” the protagonist says, to which the postmistress smiles and says, “Oh, no problem.”
Let me just say that I don’t think the “no-problem” frowners would have, um, a problem with that postmistress. As others have noted, I think it is less the usage that is the problem than the people with whom the usage is associated. A friendly Irish postmistress of advancing years–charming! A Black teenager who may not be making eye contact–sacrilege!
*There are two uses of “no problem” as a response to “thank you”; I’m focusing here on the response in a retail setting or other quid pro quo situation. I found many uses of “no problem” before the mid-nineties, but they were all in a doing-someone-a-favor situation. “Thanks for the ride; I would have frozen.” “No problem.” “Hey, I sure appreciate your help with the move.” “No problem at all.” No one complains about that usage, in my experience.
