This quote by Hunter S. Thompson is a funny method of expressing the frustration that can come with being provided suggestions. It indicates that when somebody is offered recommendations, it can be viewed as purchasing from and irritating. It suggests that the individual giving the advice thinks that the person getting it is not wise sufficient to determine the option on their own. It also indicates that the person offering the suggestions is wise enough to know the answer, which can be seen as condescending. This quote is a pointer that advice must be provided with regard and understanding, not as a way to belittle someone. It is a suggestion that everybody has their own wisdom and ought to be permitted to make their own choices.
