This is quasi-similar, but DW and I went on our honeymoon and one of the stops was in Tunis, Tunisia. We got suckered into buying a rug from a rug merchant (the salesmen there would be millionaires over here if they just applied 10% of their skills here). Anyway, we vowed not to use any CCs on the trip (probably because we didn't have any). We paid with currency, but didn't have a chance to exchange while there.
So, I whipped out by BofA VISA debit card to by this rug. We purposely kept only $300 on the chking acct. And the purchase topped $200. I clearly and vividly remember handing the card to the salesman. He then took the card and I watched him handoff the card to another. Then, like it was synchronized, he handed it to someone else who I followed as he exited the building with the card. The first salesman stopped me at the door and I resigned myself to the card's fate.
Well, that was the only time we used the card, but when I got home, I noticed our checking was overdrawn by about $100. We were closing that acct anyway because of account consolidation from marrying, but the bank said they cancelled the card because of multiple attempts to use it and suspected fraud. Turns out 3 other purchases were made after ours and over a dozen attempts to use it after the balance exceeded $0.
I guess the point is this: carry multiple cards, keep them separated, and have plenty of cash in hand just in case. Had we relied on that one card, and if it were a CC, we'd be in big trouble.
