Is the salesperson selling ads or selling goods? If she's selling goods, she can show me all the alternatives she wants!

If she's selling ads, she should not pretend to not hear me say KitchenAid unless KitchenAid pays her enough to "understand" KitchenAid.

Vendor specific sales incentives and brick and mortar retailers charging vendors to be more visible than competitors are sales of active and passive advertising respectively.

Retailers have income streams beyond what shoppers provide directly. They sell access to your attention like Google and Facebook.
