My favorite variation is the, "well yes, you did buy seat heaters in your car, the hardware is there, the software is there and you over paid for all of it, including taxes. Now, that'll be $10 per month for us to enable it".
Except that the IBM one is B2B, preceded by negotiations.
But then, what is important is what the customers were told they are buying. And while IBM didn't sell anything they didn't deliver (on the mainframe business), the cars are sold through 3rd parties famous for being sleazy, so I'd bet their customers experience was all over the place.
