I feel a bit inclined to defend BB / Magnolia. In general, they have employees that know more than nothing. They are salesman… but people as well… so some are great some good and some not good. They sell low end and mid-fi to mostly people that know little to nothing. It is there job, and not one that pays six digits. So, within that context, they usually do pretty good. I have met some really enthusiastic pretty well informed folks there… although not the most common. I haven’t met too many sales people that were just pushing stuff. If they sell something inappropriate it is more from lack of knowledge.
You want high end, you go to a high end store.
