I would tend to say that the buyers will — and perhaps to an ever larger degree — also judge the BRAND by the person selling it. A brand has values, whereas the product has attributes (f&b) and, to the extent these values are re-presented (incarnated) by the salesperson, as goes the judgment of the salesperson, so goes the judgment of the brand. A brand, a product and, of course, a service are to be experienced, and the sales experience is a cornerstone.
