From a Georgian friend (SPOILER)
The couple went to Xencureti (or Khevsureti)
[http://www.cenn.org/Magazine_1/legends.html]
There are about 40000 people and very traditionalist. Almost each family line (by family name) has their own "holy" place.
Here is the "incident" dialogue:
Young Boy: She was the one who pissed in our "holy" place.
Guide: No, she was not the one.
Old Hunter: The boy never lies.
Young Boy: Yes she was.
Old hunter: Let me see (and he aims the rifle).
Guide: Drop the rifle.
Old Hunter: Do not worry. It was a joke (and lowers the rifle).
I'll give him something so that he will not be upset.
(He gives the glasses saying "take it - it is useful in the mountains".)
Alex: (Wants to give something in return because he does not understand what is happening)
Hunter: (refuses) If you want to give it - give it to your girl.
It is my understanding that nothing would have happened to the foreigner, but if he had been Georgian, and if he did this intentionally, there might have been an argument.
