But can't every thief claim the laptop they picked up was "abandoned" too? I mean it was there on the table and no one was around at the moment.. If the customer owes him money and he is selling the laptop to get that money because the customer is choosing that outcome, then in a sense he is selling the laptop on behalf of the customer. For this option to be available to the customer, it seems they should still need to prove it was properly purchased. It still seems like this creates a loophole otherwise. What happens if a theft victim spots their laptop being used by someone who purchased it legitimately from a shop like this?
