Answer: lack of trust
Step-by-step explanation:
From the question, we are informed that Horizon Trading wants to be paid before a consignment is shipped while its importer in Italy, Friggo Imports, wants to pay only upon receipt of the consignment.
These conflicting preferences of Horizon Trading and Friggo Imports are most likely a manifestation of lack of trust. We can see that both parties do not trust each other which is the reason for the differences.
