Job search update

Had an Interview with the Shanghai hiring manager, he said he has learnt German some 16 years ago, he told me "Morgen" and "Auf wiedersehen". It is funny that when I had interviews with this company, the first time I was in London, second time in Tübingen, by the third time I will be in HK. Will I be in somewhere else for the 4th interview? I haven't written back my collegue to meet him before I leave. I'm not sure if I am rude by doing this... I simply have an uncomfortable feeling when people treat me "too well" ... I hate guys showing-off to me their possessions. Hey.. I'm earning very little, but I'm financially self-sufficient, and I don't sell my affection.
