This is very true. I was briefly in retail electrical sales and the other sales people taught me fast that explaining the product to the customer was not the way to get results. I'd happily answer their technical questions and they would laugh at me and say "mate, just tell them it means it's got a better picture or sound".
That job was all about margins though. The price tickets actually had the profit margin on them (if you knew where to look) and salesmen would always be squinting at the two digit codes in tiny font and directing customers to something that would "better suit their needs" which also happened to have an extra 10% mark up to boost their figures. Premium brand SCART leads were the holy grail. Shift a £60+ SCART lead and you'd even surpass the 78% profit of the 5 year warranty you were also expected to push. I think the highest I remember was a 92% mark up
Anyway, tangent alert
but as you say it is a culture and not for everyone. Probably why I lasted just 3 months in that job and eventually found myself in customer support for a company where one of the main USPs is the level of support they give their customers.
I think the people who don't get on well in the automotive sector are often the ones who have an interest in the cars they sell beyond seeing them as 'product' and 'margin'.
