This is a phrase T uses all the time. “No problem, you’re welcome.” Everytime I say thank you, this is his response. I have always thought it was funny and he never understood why. This is simply because in German, this is one of the things you can say to a ‘thank you.’
We Americans are always taught that you say ‘bitte schoen’ as you’re welcome. This is correct but there is also another way to say it:
Kein Problem. Gern Geschehen.
