Although it is difficult to believe, in the twenty-first century there are indeed countries with large businesses that have a cash-only policy. Cuba is one of them, and Armenia used to be one. Credit cards are either not accepted or are risky to use. Looking at this issue from the point of view of the country, do you think that this policy is a help or a hindrance to the economic strength of their country? Would someone from the United States be able to do business with a company in a country like Cuba under these circumstances?
