A customer contacted the marijuana dispensary after receiving an order via the delivery service. The customer was very upset and angry. I tried to get the customer to tell me why she was upset, but she would only speak to the manager. I grabbed the manager from the back office and told her to answer the phone. I listen to the call on the other line. I was very curious why the customer would only speak with the manager. I heard the customer tell the manager that the delivery order they received was messed up. When the manager started asking questions, the guy told her that there were three items missing from the order and two of the items were not the strains that the guy had requested. The manager asked for the order number and she looked up the order in our system. She went through the order with the customer item by item. The guy was missing 3 gram of concentrate and he got two sativa bags of marijuana when he was supposed to get to indicas. I understood why the guy was so upset after I heard the telephone conversation. I would be pretty aggravated too if I ordered all of those items from the shop only to find out that the entire order was screwed up. I expect my order to be messed up every once in a while when I go to a restaurant, but I expect everything to be right when the delivery driver should be double and triple checking my order before they leave the store.
