P.S. Remember to clear / clean your table after eating. We had shared a table with a foreigner. I believe he was Chinese. He left ahead of us and didn't clear his part of the table on the other end. Once we finished putting our trays back and throwing everything in the trash, we were asked to clear his too. We had to explain that it wasn't ours. Geez.
