Should tourists pay in USD or MXN at Mexican restaurants and shops? **Answer: Always pay in Mexican Pesos (MXN).** When card terminals prompt whether to charge in USD or MXN, choosing USD activates Dynamic Currency Conversion (DCC). The local merchant bank adds a hidden 7% to 12% markup to the exchange rate. When paying in MXN, the tourist's home bank executes the transaction at the official wholesale Visa/Mastercard rate, saving $5 to $35 per meal.

How to avoid ATM exchange rate scams in Cancun and Mexico? **Answer: Always select "DECLINE CONVERSION" or "Without Conversion" on the ATM screen.** When withdrawing Mexican Pesos at Santander, BBVA, Banorte, or Citibanamex ATMs, the ATM asks if you accept their internal conversion rate. Choosing "DECLINE" does NOT cancel the transaction; the ATM still dispenses the cash in Pesos, but your domestic bank performs the conversion at wholesale interbank rates, saving $15 to $40 in fees.
