If he is genuinely interested in what he is selling you then it shouldn't be to hard to run through the in's and outs of it . What I hate is when I witness sales people in action selling people technology who don't really have a clue what there talking about. My experience with sales people in a retail environment personally is very limited because for most products I much prefer to do my own research on them that believe the person trying to sell it to me.
