Guarantee? We guaranteed it to be an automobile. We didn’t guarantee to wet-nurse it. Now listen here, you – you bought a car, an’ now you’re squawkin’. I don’t give a damn if you don’t make payments. We ain’t got your paper. We turn that over to the finance company. They’ll get cops after you, not us. We don’t hold no paper. Yeah? Well you jus’ get tough an’ I’ll call a cop.
– John Steinbeck
The Grapes of Wrath, Chapter 7. The jalopy salesman shows no sympathy for a customer who bought a car which broke down. He cynically tells him that the only guarantee he got is that it is a car. Ironically he threatens to call the law on him, when in fact he is the one selling dodgy cars, which is not quite playing by the rules.
