About a decade ago I worked for Staples, in their business center.

I witnessed, firsthand, a 'model' employee taking a printer out of a customer's cart when the customer revealed that they weren't going to buy the money pit of an extended warranty plan! Subsequently telling that same customer that the entire wall of boxed printers was on hold for 'a school' was the icing on that particular cake.

Our store had the best rankings in the district because 'we' flat-out refused to let warranty-able items go out the door without a warranty being purchased. While the official store policy was never to use those sorts of tactics, there was a sheet that was distributed to each store in a given district, posted prominently in the break room, ranking each store by how well they did selling those warranty plans, and the best store got awards and the like. Kind of a we don't condone this behavior, but if it gets results, we'll pretend not to notice arrangement, it seemed.

I got in some hot water for not pushing those warranties - I sold perhaps one a month, usually because the customer wanted it - but I had other good employee qualities that they apparently decided were worth keeping me for.

Anyway. I have no idea if they still do such a thing, but it's not a new idea.
