an answer was posted with regards to stolen supermarket goods from the door of one’s house
how can i be responsible to pay for something i never acquired? outside my door is not my courtyard??
He already acquired it by placing it in the cart. Since it is common practice here in Yerusholyim for the shops to leave their goods by the door with the acknowledgement of the buyer (especially if they have foreign workers and people are afraid to open the door) therefore the shop can not be held liable. If the buyer told the shop explicitly not to leave the goods by the door then supermarket is responsible.
