im not sure if this was home work but im doing it

the seller and the buyer.

they are polar opposites. one is trying to get the most money out of the other for an item while the other is trying to get as close to Free to a cost of a item. so each person is not there to agree with the person so they make a cost a agreement on the value of an item that is to be bartered.

so people with complete conadicting ideas both trying to do the complete opposite of what the other wants to do so there will be arguments. but why is it that the customer is now the one in control?
i bet in old times like the years 39 or some time when there wouldn't be a store for goods in 13 miles away the store owner needed you less. because you needed them they didn't need you. now the store owner needs you because there the completion now they need to serve you. so this serve is like a sub person.... let me explain they see it a thing to serve you and nothing else not to be a person and not thing more just what your needed for. because every one wants a there shit and nothing else it is that the desertions is better then the road it self. so lets say Alex's family was like that then they wouldn't have a good friend. but because they knew a restaurant is More then just food but also the people there and the road is important to they got allot more out of that resterrunt besides some food to poop out.
