when I got home and checked my bank statement, my home bank (Wells Fargo) had tacked several charges onto every transaction.
Also, FWIW, there was an article in the LA Times travel section about banks quarantining areas to their bank/ATM cards from time to time without warning because of fraud. So it's not impossible.
