Sadly, retail staff in general will push the upsell rather than punt the right advice/ device. There are very few that will actually advise correctly if it results in lower sales. There are a few yes, but very few, and far between. I've actually noticed we get much better advice (including a lower sale, but more based on our needs), from store owners. This perhaps points to a training/ skill/ knowledge issue as well- I've had store staff try to sell me dual coils that run at 0.08/0.09, to run on my complyfe.Or they buy a Twisp Cue on special at R400.
