Whether it is better to exchange currency at the airport for Canadian Dollars to Pesos, or with someone random at the airport? What factors would yo u consider, and which option would be better? (Currency exchange rate analysis) Please give an example and explain. What factors should you think about?

Ex) If the travler is offering to buy the 200 Canadian dollars for 2400 pesos, and the foreign exchange desk will sell you 10.03 Pesos for 1 Canadian dollar. Which one should you select and why?
