Don ' t forget that in some cases , its just how they do business . If you travel to other countries that still practice bargaining in societylet ' s be honest , the US has nearly lost all concept of getting a bargain with people just accepting things at face value , you ' ll find that both the buyer and seller seem to be in heated discussion but it doesn ' t actually transcend to a personal level but is considered a standard part of a business transaction . The seller and buyer clash basically . My father had dealt with such people in the construction business and basically when such an occassion occured , it came down to leveraging their rude behavior to get a lower cost for the serviceproduct as well as pressure the business not to waste his timeare you going to give me the information I ask for ? If not , then I ' ll find somebody who knows what they ' re talking about . Normally the threat of finding somebody else to do the job got the company to act straight , unless of course the person on the line is a grizzled veteran , then you ' re in for a battle of the wits .
