As I support my company's operations across Asia from Australia to India, China and Japan, I face lots of different demanding expectations. In my observation, whether we find a request unreasonable can be associated on how we have gotten used to it.
The Japanese and Koreans have gotten used to putting in long hours and foregoing their entitled annual leaves. They do not find it unreasonable at all to only take 1-2 days leave a year and let the rest go unutilized.
In many Asian cultures, bargaining is part and parcel of most transactions. Many Chinese and Indians do not find it unreasonable to be offered a ridiculously low price for their products. That is because they treat it with jest that it is a game played in life each day.
An American or Japanese who is not used to such unthoughtful and disrespectful gestures may find this an insult to their efforts spent in precisely pricing the product. Or they may just feel it is a waste of time to engage in petty amounts.
My dear readers, I would love to hear about how you respond in a negotiation? Do you treat it seriously and provide a precise and well analyzed response and get frustrated that you have to spend so much effort in a negotiation? Or do you just treat it like a game and boldly challenge the offer?
