This is probably a rookie question, but is there no way to call the bluff of a so called offer that doesn’t exist? Is there anyway to get them to put that fact in writing, or something of the sort to verify it?
I’ve heard so many stories about this happening-it’s a classic case of assymetric information, and usually when that’s the case, there is enough of an incentive for someone who isn’t bluffing to come up with the goods to demonstrate they are being truthful.
