Slightly off topic but related to hotel service and negotiating tactics in China. My wife and I stayed in a quasi-luxury facility by a beautiful lake in Guang Dong province. The hotel was almost full. The room we were given was fine, but for the fact that there was an immense slash in the window screen and all manner of insect life, including mosquitoes, had moved into the room, attracted by the light, while we were at dinner. We did not discover this until after we returned to dinner. We complained and we immediately moved to another room - what might be thought of as a junior suite.
The next morning upon checking out, the hotel sought to charge us an additional 20%. The reason was that we had upgraded our room. We explained about the invasion of insects and the fact that the room switch was the night staff's remedy. The staff were unpersuaded and argued that the insects were not the hotel's and, having come from outside, were not the hotel's responsibility. The front desk manager stood by mutely.
My wife, a very patient woman, tried reasoning in Cantonese and Mandarin. Finally, I, far less reasonable, asked her to tell them that they had exactly five seconds to decide to take the original room price or nothing. She did. They stood firm. We started to walk to the waiting taxi. The front desk manager approached us before we reached the door and, insisting that we had misunderstood the bill, agreed to accept the original amount.
Since then, all of our disputes regarding service at virtually all establishments in China have resolved quickly with firm, almost obdurate, insistence on exactly the desired outcome. Different appraoches have worked in Western Europe, the US, and Japan.
Morale of story, stand very firm.
