Romania vs. Languages

I was waiting for Ella in the main square of Braşov. An old man, not looking like a bum, approaches me and says something in Romanian.
I reply in English,
- Sorry, I speak English.
He replies with a perfect German,
- Sprechen Sie Deutsch? (Do you speak German?)
I reply in German,
- Ja, ich spreche Deutsch. (Yes, I speak German).
He continues in German with the well known phrases,
- I am hungry, can you give me some change so I can buy something to eat....
I give him some coins and he asks:
- Are you from Germany?
- No, I am from Turkey.
He opens his eyes with amazement:
- But how come you speak German?!
Me thinking, "hmmm I have the same question for you"
- Well, I learned it at school.
Even with greater amazement: 
- Wow! Thank you very much.
and he leaves...

The day after, I am in Sibiu. After having lunch, I go to the cash register to pay the check. I hand in the money to the waiter, he gives me the change and says: "Thank you, nice to meet you!".

For another lunch, I end up in an (almost) empty pub in Raşnov. The only other customer is a guy who got already drunk at midday. The radio plays "Boys, Boys, Boys". He sings to me loudly "Boys, boys, boys, I loveeeee uuu" and offers his drink to share. I tell him sharp "Go back and sit!", but bursting in laughs the moment he turns away. The waitress apologizes ten times but does not want to accept the fact that I am not Spanish (!).
