Exactly Kiddo. Look at that Romanian lady at 02:30, she didn't understand what that guy was asking and asked "You have to translate". That is the right thing to do because she did not understand his accent or whatever he was saying. Also she did not require to give answer in English. Sure that guy was trying to humiliate these foreign people because it's his job but you have to defend yourself otherwise what is difference between him and an average nepali person who doesn't speak English?
