When you eat out, I've noticed they give you the check right away, pretty much as soon as you order. Another thing I've noticed at the places I eat out is they give you your own pot of iced water or hot tea without needing to ask for it, and even though I'm by myself. I love it, the tiny pots and pitchers are so adorable!
I have been getting more friendly with the receptionists and various hotel workers who are around. You have to pass the front desk to go in or out of the hotel, and I always smile and greet them or wave. They looked confused and surprised at first, but now they always smile and greet me on my way in or out. I'm sure they rarely (if ever) have people staying as long as I am, and I doubt they are ever foreigners...might as well be friendly with everyone if I'm going to be living out of here for awhile! I'm sure I'll start calling them unni and oppa soon, they are all so nice to me and look after me well :)
