If you go to a fine restaurant, jeweller, clothing store or car dealership then you will often meet this same behaviour. The arrogance is intended to pass the message that "we are highly discriminating and what we offer is the finest you can find". These dealerships also expect respect and that you are genuinely interested in a purchaase and not simply scouting out components. (fair enough if they have a lot of expensive inventory).
If you get quickly ushered out or ignored then it is possible that your appearance/behaviour is letting you down. An old saying applies, "when in Rome, do as Romans do!"
