First thing that comes to mind is a young man in Tokyo taking me and my then-gf to our ryokan after we asked him for directions. He walked over 20 minutes with us, clearly using up his entire lunch-break at work, to get us right to the door, going completely out of his way. We were just asking for general directions, but he took us all the way. We couldn't believe how gracious he was, and luckily we were able to gift him some chocolates from our home countries. Not a good lunch, but I hope he enjoyed them.
