It’s a real story about goods delivery. Express charge is vary much for different weight,for example,express fee is 60 RMB per kilogram for 600kg, and 30 RMB per kilogram for 500kg. But because of the delivery staff didn’t notice this or call to communicate the situation,he delivered a large cargo by one container instead of two,which caused a loss of an iphone at least. This story reminds that we have to stay alert and treat every thing seriously,keep our own responsibility in mind to avoid any unnecessary losses.
