Appart from the fact that the analogy isn't nice, you seem to misunderstand the process of haggeling. I personnaly don't like to haggle or people who try to haggle with me just for the sake of efficiency. But in some places or with some people haggeling it is a must do if you don't want to end the day as a chikken without feathers. In north Africa and Middle Est it is common practice. So in south of France where many north Africans are living, haggling is an expected practice when making deals from person to person. If you are not doing this, then you are considered to be an idiot.
