It is his job to be friendly. It is his job to sell things to you (you have to admit that he did succeed).Originally Posted by madwolfnemesis
Of course, what he actually sold may not be what you need & his approach may be misleading. In such situations, it is still 'caveat emptor', as you were not pressurized into purchasing it (not like the time-share sales tactics) or subjected to duress.
It is not easy to do research on your own, especially if you are a newbie. Suggest that you bring a friend who has been a long time hobbyist in future. Not only can your friend help you in choosing, he/she can bring you to the better known shops.
