How the scam works:
If you are in a different country as a tourist, chances are you’ve already been a victim of this scam. Most restaurants, shops, and local hotels have their own currency conversion rate and don’t adhere to bank’ rates. This means that every time you pay with your credit card you are charged extra money without knowing it.
How to avoid:
Your best bet is to have local cash for everything. Pay by credit card only at well-established vendors. The smaller the business, the bigger the charges. Also, currency exchange booths are sources of several scams; from somebody causing a diversion while the teller counts the money (making sure you are not paying attention to his fingers) to the delivery of the money in an envelope, so you just pick it up, put it in your pocket and leave before counting. Always ask for a receipt, as well.
