Hi Old school,
Seems like the sales team got their sums wrong with your lad.
My friend worked in car sales all his life and he always maintained that the most important thing was to make eye contact first and then to follow up with the sales chat. He said,you might not make a sale right away,but you make a contact,and if you got it right,they would be back. He had the best sales record in the team !
Seems like some others have a lot to learn,a young guy has to start somewhere,but then,I,ve been there,seen that.
