And you actually believe that (1) this one sided story is the truth and that (2) even if it is that verbal agreement is enough in a case like this? I'd expect the vast majority of the people that you made such an offer to to treat it as a joke and if it wasn't to teach you an object lesson in what is and what isn't a binding offer. To treat this as a study in contract law is weirding me out on multiple levels at once, Feynman's, and those that think this is a normal interaction between people. Revolting, really.
