The Libertine Approach Seems to Make Sense in a Sales

The Libertine approach seems to make sense in a sales situation,EXCEPT that:

A) it is difficult to choose actions that hurt no one involved in a situation
B) doing only what is accepted by society can limit a salesperson's actions
C) bribery and other forms of ethical breaches are not always discovered
D) two parties cannot always reconcile their needs,and a third party may need to intervene
E) "what the market will bear" is not always easy to determine
