It appears not all cow owners are honest then. Before i sold Juniper last year I had her scanned, so i could advertise her as sold as seen, empty, bulling etc. But I've known folk buy stores through the auctions and a few weeks later, if they are lucky, weedy calves born, if not lucky, elephants due to the corn the mothers have been scoffing and expensive vet bills. Even the auctions (around here) do ask that all store females are pregnancy tested "just in case". Besides, I would want to know so the cost of a vet and a scanner would confirm either way. But that's me.
