Bobyb regrets to say that more and more around here, you hear "No problem" as a perfunctory response to "Thank you" instead of the traditional "You're welcome". This is mostly from young people working as checkout clerks, or at fast food outlets, snowball stands, etc. I hate it.

I hate "no problem" as much as I do "Enjoy!" And when a waitron comes to take your plate but first asks, "Are you still working on that?" I want to stand up and scream, "this is not work!!"
