The attitude in unacceptable, but not surpassing. A couple of years ago at Hunt's Photo Expo (Boston, MA) the Nikon rep asked, in the most condescending tone, "Do you know how much this costs?" requiring that I answer, before handing over a 80-200/2.8 to mount/handle/examine. You can shop for a car and the sales reps will trip over themselves to let you take their most expensive model for a test drive. Same applies to real estate agents and homes.
