Relationship with professors

People in the university have a very strange relationship with their professors compared to Finland. The professors bring us for dinner and we might go and have a beer together. They even call students to their private phones to make sure that they have understood the tasks on the course. You can imagine how shocked I was when during the first weeks in Korea I answer my phone and there is my professor asking my opinion about the course webpage!! This Friday however, was the strangest experience ever. Our professor brought the whole class to all you can eat and ALL YOU CAN DRINK buffet instead of making a final exam and naturally paid everything. The grades would be given based on how much you can drink. The professor showed example and poor Asian students could not say anything against the authority. Me and another Finnish guy were the only ones walking out of that restaurant, others were either crawling or carried.
