Skimmed
Perennial problem using credit cards, frequently in the UK and almost a certainty in places like Thailand, Nigeria, Indonesia etc.
The one sound piece of advice my friend PC Plod told me was NEVER, EVER give your card to anyone, anytime, anywhere to swipe. Absolutely insist that you do it yourself, otherwise you will get skimmed eventually.
Buddy of mine just bought a couple of coffees from a well-known coffee shop chain at Paddington station and by the time he got off 3 hours later he was 5,600 pounds lighter, having purchased flight tickets in Miami, 2 scooters in LA and a boat!
