I think saying "no problem" is kinda rude, but it's so ingrained in me / the people around me, that I've found it easier to replace with "no worries" instead of "You're welcome".

Why do you think no problem is rude?

[nikdaheratik]

yeah, "no problem" in this context is more like "no biggy" than "it's fine (go away now)".

It sounds a bit rude to my ears. It's like 'fine'. Nobody who says 'fine' is actually fine.
