I ordered 20bags of rice (40lb) each bag. The chinese or vietnamese driver is so rude. He just throw the bags of rice on the floor. I asked him nicely to put it on top of the case. But he keep on throwing it on the floor. He doesn't speak english. I demonstrated him to place it on top of the crate since it is the rule of food handling. I reported to my agent Bao (Agent Rep.), he said the instructions from the headoffice is just throw it inside. Becausee of COVID... Seems that both of them misunderstood the instruction
