Commenter Nightwoodkitty, in response to my post about manners, wished people would say "you're welcome" when thanked rather than "no problem".
The local paper has a phone-in comment line and this appeared today:

• I'm calling about the watering down of our manners. Whatever happened to "you're welcome?" Now the clichéd language is "Not a problem." What's that? What happened to "you're welcome?" It's being dumbed down to these soundbytes. The only problem I have is people saying "not a problem."

Ok, all together, in unison, "You're welcome".
