What are the consequences for a seller who was deceived by a customer, and the customer swore falsely, and the seller did not inform the grocery store owner of that?

The worker is liable in this scenario because he was negligent in believing the buyer without proof. The default is that the price has not been received, and the seller's word is accepted regarding the receipt of the price. The worker must inform the shop owner about what happened. If the owner forgives him, then otherwise, the worker must guarantee the item and the amount he gave to the buyer.
