Learn English – What happened to “You’re welcome?”

In common conversation in the US Midwest I rarely hear "Not at all" or "Don't mention it." "No problem" is very common, and "You're welcome" is also pretty well-used.

My personal usage:

I use "Not at all," "Don't mention it," and "No problem" when the activity I'm being thanked for was really no big deal. I use "My pleasure" when emphasizing that I'm happy to be of assistance (often in a customer service context), and "You're welcome" when the action prompting the thanks was a little bit of a bother. In essence I use different phrases to indicate how "thanks-worthy" the activity was.

That's probably not common usage, though.

EDIT

I think I misrepresented what I originally meant, so here's a little clarification.

If someone thanks me for something I always do (for instance I always cook dinner in our house) then I would say "No problem" or "My pleasure" depending on context. If I did a chore that was someone else's responsibility, I would say "You're welcome" even if I was happy to have done it, because it took an extra effort on my part, not because it was a "bother."

If someone says "excuse me" to get your attention, the response is "I'm sorry, yes?" or something to that effect. If they say "excuse me" because you are in their way, then the response is to move out of the way and say "I'm sorry" or "sorry". And if they are saying "excuse me" in a loud, drawn-out, sarcastic way, the proper response is to tell them the 1980s called and they want their dated pop culture references back.

At least that's what I do.
