I usually say place names in the local dialect

That seems like the best way to communicate.

except if its a language i speak

So, if you speak a language, you don’t care what the people you’re speaking to understand?

Oh, this is German, I speak German, I’ll tell Dave it happened in Agram

“So, I the guy went to Agram”

“Wait, what’s Agram”

“Agram, that’s the German name for Zagreb, Croatia. I speak German!”
