Are members of the backpacking community really being well served by salespeople in outdoor stores selling stuff this way?

I am certain that such a question would never cross the minds of those particular salespeople. It takes a sort of miraculous restraint to sell a minimum of stuff to people who come in asking for "the works". But couldn't the salesperson at least show them some proper poling technique before they leave the store? It isn't like people are born knowing all they need to know. Someone has to show them.
