I've always found AD staff to be poorly acquainted with what they're selling. They're at a disadvantage because they have to be familiar with so many different brands and models whereas I have usually done internet research on the few specific models I'm after. But then if I'm supposed to be getting a 'luxury' experience perhaps they could back up the show with some substance. It's not just gaps in their knowledge: it's the bluster, confusing models with each other, or downright lies that really dispel any disbelief I might have suspended over this being a luxury experience. When brick and mortar stores are trying to justify themselves versus online retail, they fail on the very first expectation which is to know their product.
