When the sales slip you are presented to sign has both an amount in local currency and an amount in your currency listed along with an exchange rate. Often the clerk will tell you the amount in your currency is unofficial and shown just for your convenience which is a lie (one of a few they use to try to sucker you into falling for this scam).
If you read closely what you are being asked to sign it will say something to the effect that you were offered the opportunity to pay in local currency and declined to do so and accept the conversion rate being used as final.
We went through what you should do. Ask the clerk to void the transaction. If he doesn't ask to see the manager. If you can't get them to void the transaction, don't offer to pay cash. Cross out the amount shown in yor currency, write on the slip local currency not offered and tell the manager you will be disputing the charge and when you get the bill, dispute the charge. MC/visa MUST charge it back to the merchant as they will not have a signature showing you accepted the charge. Has worked for me every time I've gotten involved with this and they have never failed to charge it back to the merchant. Only way to deal with the situation. If the merchant gets enough chargebacks, maybe they'llo stop trying to cheat their customers with this garbage.
